Hello everyone! I'm new here... Just got a new MacBook Pro 2.4 Ghz and am new to Mac in general... I have a lot of PC keyboards / mice and one is a Microsoft IntelliMouse Explorer 2.0 and is very precise on all of my PCs but on my Mac it's really awkward and doesn't move at consistent speeds. Any ideas on this? Is it Mac related or should I get a mouse designed for Mac?
