Recently on my Mac Pro I have been experiencing phantom clicks and other strange behaviors. I have been rummaging through my system preferences to try and root out possible causes, and recently came across a strange finding in the Exposé panel (the keyboard modifiers are there from my taking the screenshot):
I have had a Logitech 2-button mouse with a mouse wheel for years, and have never had a problem with it in the past. In addition I am running OS X 10.6.8 and have not had any issues like this up to this point.
Is this a known issue? Is the extensive mouse listing a red herring? Are there any fixes for either issue?
