I’m working the trial version of Visual Studio 2008 on a C# [ASP.NET](http://ASP.NET) website. I have the Toolbox up and pinned. If I run without debugging, all is well. If I run with debugging, after execution stops, the Toolbox is still there, but all the tools are gone! Why?

Thanks for the suggestion Imasquare, but that tip was not relevant to my problem. Anyone else have any idea?
