Oh yeah, this is an odd question, but I wouldn't have it any other way... Stuff: Windows XP Diablo II LoD (latest patch) Logitech Mouseman Cordless (latest drivers from Logitech) I want to know if there is a way to enable the third and fourth mouse buttons via a registry hack of sorts. I don't want the mouse drivers installed.. Just straight up support from Windows' default mouse driver. Is this possible? The reason I ask is because Diablo II LoD is having some difficulties on another PC working with the mouse wheel and the fourth button at the same time. The funny thing is, the drivers work find with my Logitech Cordless Optical. It's on or the other.. I can't use both. Here's what happens. Drivers uninstalled: Drivers installed: I've tried many different things that were "supposed" to work... I disabled the mouseware crud.. Made sure "MS Office Compatible scoll" was unchecked. I've even done some guesswork tinkering with the logitech drivers.. Used older drivers... Played with EnableWheelDetect in the registry.. Nothing seems to work.. It's an odd problem.. And I have reason it might be due to the game itself. I'm going to reinstall it and see what happens (Because it used to work). Until then though, I was hoping someone had experience this kind of problem.
