AutoHotkey Community

I posted this on the Ask for Help forum but got no solution to this problem. I'd be interested to see if the following error can be reproduced.

I'm building a keyboard buffer with #UseHook, but it seems that when typing fast, keys are occasionally sent without triggering their associated hotkeys, as if AHK were off.

The problem occurs with the following script file, which I am including in full:



When I open a blank Notepad document and strum the J, K, L, and ; keys, I should get only a, b, c, and d, but I am also seeing l's and ;'s appear in the typed text. This is strange to me, because nowhere in the script do I include an instruction to type l or ;.

Now, for some reason, the problem disappears when I comment out the #UseHook directives. I get only a, b, c, and d when strumming J, K, L, and ;, as expected.

What could be the cause of this? Is this a bug?

I am using AutoHotkey_L v1.1.00.00 with Windows 7 Starter on a newly-purchased Toshiba netbook.

I was unable to produce any problems using the script and instructions provided, with v1.1.00.00 on Windows 7 x64. Perhaps it is a matter of timing - my system is somewhat faster than the average netbook.

I did some retesting on my computer at work, and the problem still seems to occur. I found this bug while trying to implement a keyboard buffer and typing at ultra-high speed.

Work computer:
Windows XP
AutoHotkey 1.0.48.05 (not L this time)

I also tried using a 'keylog' variable, which seemed to work much better. However, every now and then a missed keystroke turns up, as if AHK isn't recognizing it.
