..I was using map[] and beta and is this a bug ?. But I coded this sampler and is not a beta thing, is an production thing too.
Is the code as presented supposed to fail ? ( found viable solutions, so this is not an OMG! kind of thing )
I believe that the logic would work if not GuiOnEvent mode.

Edit: Tried in v3.2.12.x and v3.3.8.1 and is a design thing. Not new. I just never noticed it.

I've used OnEventMode with multiple GUIs before (for example my PlasmaKit script).

Perhaps, something like this?

#include <GUIConstantsEx.au3>

Global $iExitLoop = 0, $hGUIParent1, $hGUIParent2, $iLoadGuiTwo = 0
Example1()
;~ Example2() ; not an example but a GUI ?
Func Example1($iParent = 0)
    Opt("GUIOnEventMode", 1)
    $hGUIParent1 = GUICreate("Parent", 400, 300, -1, -1, -1, -1, $iParent)
    GUISetOnEvent($GUI_EVENT_CLOSE, "OnEvent_CLOSE_ONE", $hGUIParent1)
    GUICtrlCreateButton("load GUI TWO", 8, 8, 100)
    GUICtrlSetOnEvent(-1, "LoadGuiTwoFromGuiOne")
    GUISetState(@SW_SHOW)

    While 1 ; Loop until the user exits.
        Sleep(100)
        If $iExitLoop Then ExitLoop
    WEnd
    $iExitLoop = 0
    GUIDelete($hGUIParent1)
EndFunc   ;==>Example1

Func Example2($iParent = 0)
;~     Opt("GUIOnEventMode", 1)
    $hGUIParent2 = GUICreate("Child", 300, 400, -1, -1, -1, -1, $iParent)
    GUISetOnEvent($GUI_EVENT_CLOSE, "OnEvent_CLOSE_TWO", $hGUIParent2)
    GUICtrlCreateButton("say hi", 8, 8)
    GUICtrlSetOnEvent(-1, "GuiTwoSayHi")
    GUISetState(@SW_SHOW)

;~     While 1 ; Loop until the user exits.
;~         Sleep(100)
;~         If $iExitLoop Then ExitLoop
;~     WEnd
;~     $iExitLoop = 0
;~     GUIDelete($hGUIParent2)
EndFunc   ;==>Example2


Func OnEvent_CLOSE_ONE()
    ConsoleWrite('- Func OnEvent_CLOSE_ONE()' & @CRLF)
    $iExitLoop = 1
EndFunc   ;==>OnEvent_CLOSE_ONE

Func OnEvent_CLOSE_TWO()
    ConsoleWrite('- Func OnEvent_CLOSE_TWO()' & @CRLF)
    GUIDelete($hGUIParent2)
EndFunc   ;==>OnEvent_CLOSE_TWO

Func LoadGuiTwoFromGuiOne()
    Example2($hGUIParent1) ; no solution.
EndFunc   ;==>LoadGuiTwoFromGuiOne

Func GuiTwoSayHi()
    ConsoleWrite('--- HI' & @CRLF)
EndFunc   ;==>GuiTwoSayHi

Keep in mind, pressing the "load GUI TWO" button again while one is already open will overwrite the handle assigned to $hGUIParent2.  You could account for this in various ways if you intend to not allow this behavior.

      Edit: Modified the example for dramatic effect  
      Edit 2: Solved my problems at a post somewhere down this thread.

      Im not sure if this is intended but normally Autoit variables are always passed as copies (except objects i think).
      But below i observed an unconsistency when copying maps with nested maps inside.
      Issue:
      If you create a nested map1 and copy it to a new map2, changing a nested value in map2 will also change the nested value in map1
      Dim $player[] Dim $sub[] $player.test1 = 1 $player.test2 = $sub $player.test2.child1 = "org" $player.test2.childext = $sub $player.test2.childext.child1 = "org2" $playerold = $player ; make a copy of the whole map ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF); original nested value in $player $playerold.test2.child1 = "changed" ; edit a nested value in $playerold ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF) ; original nested value in $player changed ConsoleWrite("---------------------" & @CRLF) ConsoleWrite("player.test2.childext.child1 : "& $player.test2.childext.child1 & @CRLF); original level2 nested value in $player $playerold.test2.childext.child1 = "changed2" ; edit a level2 nested value in $playerold ConsoleWrite("player.test2.child1 : "& $player.test2.child1 & @CRLF); original level1 nested value in $player stayed the same ConsoleWrite("player.test2.childext.child1 : "& $player.test2.childext.child1 & @CRLF); original level2 nested value in $player changed

      As the title says, when a script that is stored on a Google Drive File Stream drive is ran or compiled, it fails to work at all.
      Basically, Google Drive File Stream creates a G:\ drive where you can access all your files. The difference between this and Google Backup and Sync is your files are downloaded as needed rather than they always be downloaded and taking up storage. 
      How to Reproduce Bug
      1. Download and Install Google Drive File Stream
      2. Sign into Google Drive File Stream with a G Suite account. 
      3. Create a AutoIt Script and save it to Google Drive File Stream. (See attached file)
      4. Attempt to run or compile this AutoIt Script. 
       
      AutoIt appears to act like the script is (incorrectly) empty and ends immediately. (You can kind of tell based on file sizes from a successful and failed compile).
      I've also attached a Process Monitor log file. Hopefully someone can figure this out, because having to move the script out of the drive just to run or compile it is super annoying and I lose version revisioning Google Drive provides me.

      WinSetState ("[CLASS:OpusApp]", "", @SW_SHOWMAXIMIZED) and WinSetState ("[CLASS:OpusApp]", "", @SW_MAXIMIZE) don't maximize the window.  Using WinSetState("[CLASS:OpusApp]","",@SW_RESTORE) allows me to maximize it about 15% of the time. I've tried using  WinMove("[active]",0,0,@Desktopwidth,@Desktopheight), but that only makes it worse. I've also tried putting in a sleep and maximizing it again. Does anyone have a solution?
      Here's my code:
      The startup script is intentionally commented, because I'm not testing it right now. The other comment is just for debugging when I need it. 
       
      UPDATE: When I run two instances of the program, it works almost all the time, but if I copy the code inside the else statement twice it doesn't work at all (despite the fact that it's running the same code just in one program vs two). I also noticed that when I run two instances of it, about 50% of the time when it opens both the windows, it also hits the windows button and types the letter d into the search box. Neither of these actions are in my code. I'm not really sure what's going on.
