On fvwm2.6.7-3 (ubuntu18 running in hyper-v on windows 10):
- peak meter control dialog opens always maximized, restore/maximize button present and is enabled but does nothing. Minimize button present and works.
- auto mixer control dialog resizable larger than allowed
- auto mixer mic options dialog too small. Minimize button also present (not shown in Windows), which hides the dialog, fortunately you can alt-tab back to it.
So only change from xfce is that control windows have minimize button, even in control dialog it shouldn't have.
