i have got a logitech MX revolution, an excellent mouse. when i got my mac i installed logitech drivers and it worked fine. i was able to go to system preferences and then click on the icon and change different options. because there was a known bug in world of warcraft on mac with logitech mouse i had to install 'MouseSteer' driver, and that stopped the bug. but it was only a 30 day trial. and didnt really like the software. now that i have uninstalled that from the system i decided to reinstall LogitechControlCentre. but after a successful install the mouse is not recognised in the LCC under system preferences. but it does move and click. something else that is also occuring is that the mouse pointer is acting strange. on the dock the icons are not moving or zooming in. when in a menu things are not being highlighted when the mouse moves over either. i know that it is not a problem with the OS as i have a wire, 3 button mouse that works perfectly and things are highlighted and the dock is fine. i do not want to reinstall Mac OS X either as i simply do not have the time to reinstall everything. and time machine backup system is not active at the moment.
