I recently upgraded to OS X Yosemite. Everything works fine but for some odd reason my cursor fails to highlight (provide feedback on anything I hover on any options).
As an example (if I'm not explaining this very well):
When I hover over the options in the Safari menu (or any other menu, nothing shows up as a blue background as you would expect (it only turns blue after I've clicked it).
I've been running Mavericks for a long while, and I had no issues.
I'm not sure if the mouse has a part to play, I'm using Mad Catz R.A.T3, anyone know if this as an issue with Yosemite? Or are aware of a fix?
