"Not Apple certified, and I sure found out why, fast."
Fixed an old Macally Dotmouse, reversed scroll-wheel action. The Dotmouse preferences in System Prefs wouldn't open (grayed-out 'continue' button, no solution). BUT...
...USB Overdrive then made a shambles of the other installed wired/wireless USB devices' functions.
(From the get go, this app will 10-second delay nag you for a donation every time you go into its prefs, which is terrible when fixing something
I carefully followed the vendor's instructions that were supposed to work around these (known) issues, and eventually wound up with a mouse-pointer stuck on the apps pref drag area like your hand stuck on duct-tape. Clobbered the keyboard. Couldn't do force quit. The disable changing other peripheral's function didn't work, and it started adding sound functions (!?) to the mouse's function, and a whole list of bizarre anomalies. It was either kill my brand new Mini's power switch, or figure out something less drastic.
So, just pulled out the mouse's usb and put back in. Now I could force-quit System Preferences altogether. Then I could set to work. Almost hearing the app's voice as Hal: "Dave... what are you doing Dave. Please stop...Dave...
If you like playing Russian Roulette with a brand new Mac and Mountain Lion, give this utility a spin. In the 20+ years of using Macs, I've never seen an app go so wrong so fast on such a brand-new presumably bullet-proof machine. So this is why the vendor's app is not certified, I guess.
I prefer to get a new mouse, or else learn to love the wrong-way scrolling until Macally posts a new driver.
