hi, first of all i am completely in love with AHK and my brain cannot stop working out new ways of automating my life...

now to my problem however..
i run AHK on my new XP machine at home and it works perfektly. but on my NT-machine at work it seems to freeze the mouse pointer (sometimes for several seconds) whenever i have clicked the minimize button on a window.

when i check the cpu usage it runs idle at 0% even with my ahk application running. but still the mousepointer freezing problem...

i should add that other than the above described problem i find the computer running pretty smoothly... but still this problem is a bit annoying.

(BTW, is it ok to use AHK within an orginization?)

cheers!

Are you sure the problem lies in Autohotkey? I remember a topic similar to this a while ago, in which the problem actually turned out to be spyware.

thanks alot for your reply!

as soon as i exit the AHK app the mouse pointer no longer freezes like this. but still.. maybe i can try it on some collegues computer to see if the same thing occurs there..

Also, by "AHK app", you must mean a script you wrote, correct? Perhaps you could post the source for that script here so we can see if there's anything wrong with it?

hi everybody, and thanks alot for all your tips!!!

i removed everything from my script and added it back little by little....

..and i found out that these lines triggered the mouse-freezings:

Shift & WheelDown::AltTab
Shift & WheelUp::ShiftAltTab

So now the only question is: is there a better syntax for this...

thanx again!! Wink

That's strange, again. I've never encountered performance problems with the Alt-tab actions. You could try reproducing the hotkeys using regular keystrokes, and if it works it might be a bug in the Alt-tab actions.

I don't think it's the alt-tab actions, but rather the fact that they're assigned to mouse hotkeys. Mouse hotkeys automatically cause the script to install the mouse hook. Since all cursor movements must pass through the hook, if the script doesn't get enough CPU time, the cursor will get stuck or lag behind your movements of the mouse.

Usually, setting priority to High resolves this:
Process, Priority, , High

If it doesn't help, turning off window animation might reduce the problem. If these things don't help, perhaps there is some other kind of problem at work here.

You should have window animation turned off anyway. Confused

again thanx,

as a matter of fact when i add the WheelUp/Down:: hotkey to my script on my own XP machine the same kind of mouse delay/lag occurs in the exact same way, and it does not make a differens if I remove windelay or if I set process priority to high.

so i go with the theory that the mouse hotkey funktion actually is the problem here.

I can't explain or reproduce that (but I don't have window animation turned on). The only thing that comes to mind is turning off window animation.

It is normal to get mouse cursor lag sometimes, such as when a mouse-hotkey script launches an uncached document.

To anyone else who uses mouse hotkeys: Have you noticed this behavior?

Edit: I think this is a known issue for which there's no easy solution (other than turning off window animation in the OS). For details, see: http://www.autohotkey.com/forum/viewtopic.php?t=9013
