Did this start right after you ran a system update? Check to see if your version of Flip4Mac is up to date.
Also try creating a new user profile. If the problem does not exist in the new profile the issue is probably going to be found in:
/Users/"YourUserName"/Library/
Preferences or Caches with Flip4Mac in the actual file name.
