Access violation errors with PL/SQL developer

[AlexS]

7.0.2.1076 version of PL/SQL developer hangs and gives access violation error:
I have to open Windows Task Manager and end task in order to close it.

I encounted the following error:
--Access violation at address 60FA977C in module 'oracommon10.dll' read of address 02CF6E03

Maybe this is an environment problem. Can you go to Help > Support Info, press the 'Copy all pages' button on this info screen, and paste this text into an e-mail reply?
