Problem with two-finger swipes on my magic mouse. Is there any form of fix? Recently, I've migrated from a strict Windows to a OSX environment.  I'm using the Magic Mouse as my pointing device and so far I've been satisfied.

The only problem that I am having is that I can not get my mouse to consistently recognize my two-finger swipes to swap between my full screen apps.  It does work but only occasionally.  Specifically, I have to swipe about 30 times before the screen will actually switch to the other application.  Also, I know that the mouse is partially picking up my gesture because the window will begin to barely transition, but I usually can't get the screen to shift any more than a couple inches on my 27" display. 

This is unusable.

Are there any gesture sensitivity settings that I may be able to tweak, buried in some form of an initialization of configuration file?  Or, am I stuck and I'll have to simply avoid using this gesture?  I think this functionality would be very useful.  For now, however, it's not an option.
Try this little utility: http://www.magicprefs.com/

It allows you to override mouse gestures, map them to your own actions, etc.
It also has a graphical view to show you what you're doing, which can be very useful in figuring out what you're doing wrong.
