Ondrej Pokorny wroteI have 2 monitors on a win 10 machine and I am not aware it should
behave like this (you either duplicate the task bar or you have one task
bar on one display with all windows, afaik).
As the original reporter wrote, it is an option to display the TB button on the display where a window is (I think that's the only sane option, btw).
Same problem exists in Delphi, the problem is that the TApplication window always lives on the main monitor.
Setting Application.MainFormOnTaskbar should help, but does have some consequences, so be sure to test.
