Very, very, very odd mouse problem..

[Celeras]

Here's the jist. Sometimes after playing World of Warcraft for a few mins, the cursor will freeze on my mouse. Not just in game but on the desktop as well. JUST the cursor freezes, the mouse still works fine. You can still right-click/click whatever you want, even though you cant see where you're clicking. If you're good, you can 'ghost' the mouse to the start tab, and restart the computer the old fashioned way, in which case the problem goes away. It cant be any power/driver issue, because the mouse still works.. it just the cursor that freezes. Anyone have any idea? Its only happened a few times, but its rather annoying.

Also, by 'ghosting' the mouse ingame, i can somewhat remedy the problem. In the video options, there is an option for 'hardware cursor'. If I ghost my mouse to that after it froze, and uncheck this option, the mouse now works... in the game only. If I alt-tab to the desktop, that mouse is still frozen and I have to ghost. In addition, when I uncheck this in the game, the 'normal' white mouse arrow will appear on the game screen, frozen, while im moving the game mouse around.

**[edit] It also seems that I can remedy the problem by reseting the resolution. Perhaps the 'hardware mouse' option in the game has nothing to do with it at all, then.

Any ideas? Could it perhaps be some kind of IRQ conflict? My IRQ16 is being shared by the Video card, and two Universal USB host controllers. Yes I'm using a USB mouse, this is the way the computer allocated the IRQs default. I was told that just because theres more than one thing on the IRQ, that doesnt necessarily mean theres a conflict?
Any suggestions would be helpful, this has me stumped.

Did your mouse come with a USB to PS2 adapter. If so, give it a shot.

Welcome to Windrivers. Have you tried another USB port?

I can remedy the problem by reseting the resolution.

First I'd try changing the video driver, either update or revert to an older version, see if that cures it.

The mouse cursor is provided by the video driver, and when you change resolution, one thing it has to do is re-initialise the mouse cursor display.

you've checked device manager for "!" or "X" already? i had that same problem a while back... I just lived with it for about a year, then i formatted, and it went away

The same cursor icon freeze happens for me when playing Everquest II.

GeForce 6800 GT (made by Verto). ForceWare drivers version 66.31. I have it slightly overclocked (about 5%) in both clock speeds. AGP 4x.

I think this must be a bug in either the card or the drivers. But it seems there is a workaround:

If I run either EQ2 or WoW with triple-buffering on, I experience cursor freezes. In the case of EQ2 it's intermittent, but in the case of WoW it's pretty fast and regular.

If I run with triple-buffering off, however, it seems to be ok.

Also, WoW has an option for selecting whether to use a hardware or a software cursor, and this problem never occurs when using a software cursor.
