QPC based timer seems to affect sleep

In my thread on the regular AHK forums, obeeb seems to reckon that the reason the Send seems to stop execution is that a Send {a} is actually interpreted like Send {a down}; Sleep 50; Send {a up}.

This seems to be correct.

I do have a workaround, but thought I would ask if anyone else could shed more light on the subject.

Cheers

This http://ahkscript.org/boards/viewtopic.p ... 466#p13581 seems to be the answer.

Your callback is being called on a thread other than the script's main thread. This causes difficult-to-predict behaviour since AutoHotkey is not designed to be multi-threaded. It's almost surprising that the script works at all.
