Is there MouseMode that only interact topmostlayer

[senatin]

I tried some codes to set a windowposition to Zoder or to nontopmost to allow me to take control of my cursor.
The problem is when I interact in some features of my application my cursor then dont respond to my mouse movement until It finish loading what content have to show, but I notice that when I click alt+tab or winkeys, its possible to point my cursor to another features of the same application and click.

So I desided to make a script that will send alt+tab or winkey so I can click more features alltogether, but It doesnt work either, the application block aswell those option I dont know why.
so I desided to script that the application will always be at the background so my cursor is always in TopLayer but it still didnt work. I tried to disable enable the windows state and still with no luck.
I even Combined all gathered script. Here my script

expandcollapse popup

#include <WindowsConstants.au3>
#include <WinAPI.au3>

#include <WinAPISys.au3>
