I tried to save Form1 as Form2, leaving Form1 "as is" (it's OK whether IDE leaves Form1 in Project or not).
Seems VS.NET merely renames Form1 to be Form2--not what I'm trying to get. (I want to experiment with the UI on Form2, but have Form1 in the directory just in case I prefer the original).

Should be simple: frm1 Save As... frm2, but leave frm1 "as is"

Create a new form in the project, view the code and paste all the code then fix up the name and constructor of the form.
Let us know if you find a better way.
