In BIAB 2021 for Windows, window management (especially moveabal piano roll Windows) is quite bad.

It often happens that a window remains behind, or vice versa in the foreground, while I want to display another application from the Windows taskbar.

This frequently leads me to iconize everything to find my BIAB windows.

Moreover, the maximization of windows does not always react as expected (in an environment with 2 screens).

In short, if the jobs has not yet been completed, it would be good to rationalize the Windowsmanagement and make it conform to the standard.
