The bug happens inside the gtk, so there was no useful debugging message. Can u describe/send me a simple example, where the bug shows up?

Interfering in the IDE or in the code?

If they interfere in the IDE, then this is a bug. Plz send me a short description, how they interfere or what are you trying to do. The IDE creates forms in a different way than a normal LCL application. It should simply be blind for form names. Unitnames should also be no problem, because the IDE distinguish units by the full filename. The short names "unit1" and "unit1(2)" are irrelevant abbreviations for the source editor.

If they interfere in the code, then you have two units with the same name in one program.

What stuff?

Unloading in the IDE is simply closing the file.
Removing the used unit1 from the main source can be done by Project->Remove from project.
When you created an LCL application, then the main source is hidden. You can open it by View->Units... or by open the file. Normally you don't need this file, because you can edit it via the Project menu, just like Delphi.

In this case the roadmap will be much bigger than the code. 90% of the explanation will handle the widget independency of the LCL. I will add the arc function tomorrow.
