AutoIt should return when script is finished???

Hi,
after some hours of researching i stil have no clue what is going on internally in  autoit it.
I am used to unix - so i am seeing autoit as just an another script language - which behaves very strange!


My Goal is simple. I want to start an Auto it script from an VBScript  program - and i do not want to the autoit script to return before the script is finished.

Currently i try to run the script

"C:\mypath\autoit3.exe" "myscript"

in VBScript with  "wsh.Run(cmdline,0,true)"

However if i start the autoit script (which waits until a "Busy" window disappears - Simple! )  - autoit Returns immediatly.

Even if i try to run this from dos cmdline it
this line returns immediatly - although it correctly displays a message box some 120 secondes later when the busy window has disappeared

"C:\mypath\autoit3.exe" "myscript", the script Returns immediatly

--> so my Programm continues - although the "Busy Window" has not disappeared!

However i want _not_ an immediate return. I want that autoit3.exe Returns exactly when myscript is finished - and not any time earlier!

At this point and a lot research i have no clue how to do this....

Can anybody please advise me?

Thanks!
