Kirk Rheinlander,Thank you for posting.A test of the Magic Mouse here does not replicate the issue you describe. FileMaker Pro 11.0v4 functions as expected on OS X 10.7.2 with the Magic Mouse preferences set to allow horizontal/diagonal scrolling.To help you identify the cause of your FileMaker file's unexpected quit, would you provide some additional information?1. Will FileMaker re-launch after it quits, or do you have to restart?2. Have you tested in a different user account on this Mac?(if not, try creating a new Admin account to test with)TSTuataraFileMaker, Inc.
FM restarts fine, albeit without the port settings for sharing (port in use). OS X does NOT need to be restarted.
I remain able to duplicate the error with a 2 finge swipe sideways, either direction. Crashes every time.
Thank you for the additional information. Have you been able to replicate in other users on this Mac?
Since the Magic Mouse works here in testing, we need more information about your configuration to narrow down the issue.
