Hey all. I've recently been running into problems with mouse clicks not being picked up by OS X. At first I thought it was my mouse, but it seems to happen with other USB mice as well. Turns out the problem is being caused by USB Overdrive. Seems there is a problem with it and 10.6.x. Turns out that I am not the only one with the problem and no one has heard from the developer of a workaround or patch to fix the problem. I use a Logitech MX518 and Logitech won't release Mac drivers for it, so I need something like USB Overdrive to get full functionality. Does anyone here know of any alternatives to USB Overdrive that work with Snow Leapord? Note: I have searched the forum for an answer, and the only post I could find was from back in 2006 and no one answered it. Please don't do the same to me.
