(My point is that it might not be caused by high CPU usage/no CPU time for the script.)
If the main script thread doesn't check for messages, it can't route the appropriate messages to the keyboard/mouse hook thread. However, I've seen "something similar" on XP, Vista and 7 when the process stops checking for messages e.g. I think it's too early to assume it is specific to Windows 7. So it seems to be a Win7 specific issue.FYI, I make frequent use of a mouse hook on Windows 7 64-bit, and have not encountered this problem. I was running the same AHK script under Server 2008 and XP, and did not get *any* pointer lag under those OS's. Fortunately the problem is more of an annoyance than a show-stopper for me. There's no way I am giving up my AHK script to use Windows 7, so I'm hoping a fix can be found for the problem with respect to AHK's mouse-hook implementation. I wonder if it's got something to do with Win 7's new "Windows Driver Foundation - User-mode Driver Framework" infrastructure. So I'm wondering if there is some new trick that must be used with mouse-hooks in Windows 7 to avoid being afflicted by the problem described. Like AHK, Intellipoint (ipoint.exe) runs as a normal process in user space. Though I should note I still see a small bit of pointer lag even under this circumstance when the CPU is pegged.Ī final thought: running the latest Intellipoint 7.0 driver for Win 7 does *not* cause the pointer lag problem as described. Disabling that service and killing my AHK script mostly eliminates said pointer lag. So it seems to be a Win7 specific issue.Īdditionally, I discovered that when I have my Wacom tablet plugged in under Win7, the Tablet PC Input service (enabled by default in Win 7) causes the exact same problem. So it seems that, specifically under Windows 7, AHK's mouse-hook is not receiving an adequate slice of the CPU pie, which is inducing severe mouse pointer lag along with general system unresponsiveness (e.g. I found a similar sounding post from 2004 in the forum describing mouse pointer lag under heavy CPU load. The problem only presents when the system is under maximum load - specifically, when the CPU is pegged.
I am experiencing the same problem under Windows 7 (both x86 and 圆4 versions).Īfter considerable testing I have tracked the problem down to AHK scripts which use the mouse-hook.
