Copying a Form in Visual Basic 2010 Express

[sneakyimp]

I wanted to copy a complex form I had created because there was another form that was nearly identical. Apparently this is very difficult in VB2010E. I tried a variety of techniques (copying files in windows explorer, editing with notepad to change classname, copying and pasting in the IDE window, etc.). I finally managed to get both forms to appear in my project, but I believe my vbproj file may have become corrupted because I cannot select one of the forms as my app's startup form (see attached). What is wrong here? Is my vbproj or my form corrupted? Is there a proper way to copy a form? When one imports a form, what files are needed (.vb? .designer.vb? .resx?)



Note how the form frmCategEnt is not available in the startup form drop-down.

I really don't want to have to create this form all over again. More importantly, I hope my vbproj file is not corrupted.
