Hi,
I have a Windows Form project in Visual Studio 2008 + SP1, and each time I try to edit a tool strip item in a context menu of my project, Visual Studio just crashes, I mean it just disappears (no error popup, no dialog asking me to post the details to Microsoft), and the process goes away.

I have attached WinDbg to gather the exception details and here it is:

0:000> !PrintException -nested

It looks like a bug to me, but is there anything I could do to my project, like change my form, or the layout or the inner controls, so I can edit it again. Each time I close and reopen Visual Studio, the bugis there, so I cannot edit my form anymore, at all :(

Thanks!

Found a solution ? I'm having the same prob

Hi,

Well, not really.

I modified the designer.cs file manually, removed what *seemed to be linked to the issue*, then I prayed, burned some candles, invoked ancient voodoo spells, and voilà!

Simon.
