I've just tried to duplicate an inherited window (twice) and I now have new instances "(1)" and "(2)" in my recently modified windows list, but the window does not appear in the project browser tree. 1. I think this is a bug. 2. How do I delete these windows? ---

If you save the project, does anything happen to the project browser? What if you update the project (a different button/menu item?). Finally, what if you re-open the same project in the designer? Also, what version of Ignition are you on? ---

Well, must've been an isolated event because I can't duplicate it
