Hi Erel Dbasic .exe on the desktop has just thrown these two unhandled exceptions. The second occurred imediately after continuing from the first. This has happened sporadically with Dbasic.exe ever since I started using it. It seems to be associated with commandbar.dll. This is unusual as I haven't had exceptions from any other application (except those caused by my own fault developing VB.NET code under VS 2005) since I installed Vista on this machine back in January. Any ideas?
