Both mouse buttons "stick" in game

I posted this here since it seems like a mouse driver/software problem. My sister has been playing on my wifes machine (thats machine not WoW account) its old but its enough to run one client. she has win xp pro and she uses the mouse to move and steer by holding down both the left and right buttons, however after a few seconds if she lets go her character just keeps going. she has to spam both buttons to make it stop. ive tried different mice we have around the house both wired and wireless and the problem persists which leads me to believe its software. i have updated my drivers from logitech cause thats what we use. I cant duplicate this problem on my machine even though we have the exact same OS. any ideas/

Thanks in advance

hmmm... i have heard that some people use their mouse to trigger auto-run, but i am unfamiliar with the default button for it... maybe mouse3 or the middle button (which can be right+left at the same time)

Try removing the Logitech driver completely and use the MS default driver. If you have to use driver cleaner in safe mode to remove all the Logitech driver remnants. If mouse driving works fine with the default driver then get another download of the Mouseware and try it again. Frankly, on my gaming machine I don't use the logitech software except for the game panel of the G15.

A few other thoughts could be bios issues. I have no idea what to look for but poke around in the bios and see what is there. Maybe something will stand out and you will have an "aha!" moment.

Good luck.
