Hello,

I'm having ongoing trouble with Flash Builder 4.5.1 hanging/crashing during startup.

Sometimes the following Terminal command fixes the issue:

cd ~/Documents/Adobe\ Flash\ Builder\ 4.5/cascaded/308971/configuration/.settings

rm org.eclipse.ui.ide.prefs

However this isn't a silver bullet solution, and sometimes the only way is to uninstall and reinstall FB4.5.

But this is a major hassle, especially after 3 or 4 times!

I am running Mac OS X 10.7 and have updated to FB 4.5.1 Premium and also installed Subversion/Subclipse as well as the BlackBerry PlayBook SDK.

Problems seem to occur when working in SVN projects.

I have also noticed that the Delete and Arrow keys and Right Click fails to work sometimes also.

Is there a way to reset / clear FB 4.5 Prefs / Workbench?

Thanks,

David Douglas
