If you're trying out CFBuilder, and at the same time still using CFEclipse, you may have been faced with this annoying situation where everytime you open Eclipse, you'll get something like this: <<<<ColdFusionBuilder>>>>. And it keeps adding on more perspectives every time you open either CFBuilder or CFEclipse.
Don't worry . . . there is a fix, according to JeffC in the #coldfusion channel. Simply go into Preferences, General, and open the Perspectives preference. Now you can get rid of all those unwanted preferences. Thanks, JeffC!
