Hello, I wondered if anyone had come across this problem: I am using VC2003.net to make a windows forms app. I can do it fine at home, but at work (with identical software) I get this error message when I try to view the form designer (as opposed to the form code): "An error occurred while loading the document. Fix the error, then try loading the document again. The error message follows: The designer could not be shown for this file because none of the classes within it could be designed." This occurs even with a brand new form. Please help! Thanks Simon
