When I first load my form into the designer it wll works correctly and I can switch to the code view with no problem.
After running my program or switching between design and code view I get the following error when I try and view the form in design mode
Warning 1 There is already a command handler for the menu command '5efc7975-14bc-11cf-9b2b-00aa00573819 : 17'. 0 0
By deleting the Bin and Obj directories (or closing and reopening the form) I can get rid of this message - but it returns next time I open the form (or compile my program)
By the way there is no menu on this form.
