VS2008, .NET 2, VB.NET, XP ...
I have a Windows form, with a WebBrowser control and a Close button, which just does a Me.Close. The form's cancel button is set to the Close button, so that I can hit ESC to close the form.
I set the DocumentText property of the WebBrowser control in the load event, and the HTML displays.
Running the application from Visual Studio, if I click the Close button, the form closes with no error.
If I hit the ESC button I get
RaceOnRCWCleanup was detected Message: An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss.
If I run the app outside VS, I get no error.
Any ideas a) why the error, and b) how to prevent or suppress it?
Many thanks in advance.
