handling optional sub-popups

[Jorge11]

I'm working on a script using Yashied's HotKey UDF (which I like more than AutoIt standard hotkeys), for more easy control of some other application. To do what I very often want with this other appl, I normally have to first press two separate keys (ALT + some letter), so I use the HotKey UDF mainly to be able to press a single Fkey instead of pressing two keys. But sometimes the other appl will pop-up anotther subwindow asking something, like to confirm the thing I asked for. But since that doesn't happen every time, I don't know the right way to handle that.

Here's the kind of thing I've tried, but it fairly often gets messed up and stops working / stops responding to the Fkeys:

 

expandcollapse popup

#include <Array.au3>
#include <Constants.au3>
#include <Misc.au3>

#include "HotKey_21b.au3"
#include "vkConstants.au3"

AutoItSetOption("MustDeclareVars", 1)
AutoItSetOption("WinTitleMatchMode", 2)
AutoItSetOption("GUIOnEventMode", 1)

But maybe this whole idea is no good. What would be a better way, please.
