Nope, still do the same thing.
Nevertheless, i figured out i could just copy and paste the page2 and rename it page3...
I gaves me a couple of building errors, but from the output windows, i have been able to open the new page3 designer page in "code view" then rename Page2 to page3 into it, then it finally works...
Sounds weird, i guess something might be wrong with my Visual Studio settings...
Anyways, thanks for your time!
