I can not get the class browser to load. When I click the menu option 'Class Browser' I eventually receive the error message "Invalid buffdirty call". When I click "ok" the program crashes with the following message "Fatal error exception code = c0000005 Called from classbrowser init line 0 {} called from browser line 0 {}".

This error just started today, many times I have used the class browser without any problems.

Does anybody have a clue as to what went wrong and how to fix it?

TIA
