That is the WSOD - White Screen of Darn. I do not think darn is the best description.

Look around on this forum and you will see lot's of other people with the same problem. Google "WSOD Visual Studio". You'll get a dozen different fixes, none helped me. By the way it is a "feature".

You can try this - did not work for me but it might for you.

The only way I know to avoid it is to keep your forms very simple, few components. How is that for help.

Sorry and good luck.

Thanks - I've tried attaching another VS instance, it doesn't catch any exception. I've not changed any code. I've been fighting the WSOD since before release ( and reporting it as a bug ), I can generally work it out, but all of a sudden, my entire project is riddled with them.

I am frankly astounded that someone at MS thought this was a good idea.

Another clue - I've created a brand new form, and added a button. I get the same 'window class name is not valid' error in a message box when I try to set the backcolor of my button.

Anyone ?

*bump*

Any chance of a reply from a Microsoftie ? I doubt anyone else understands this insanity.
