(setting a > stylesheet on a MDI window) Yes, thanks. Most importantly the maximizing effect. Further info: For METHOD 'A': I discovered that you can cause the bug simply by grabbing the lower right corner of the MDI sub window and expanding its geometry /beyond/ the size of the MDI area. As soon as that is done, the window freezes. >From the right-click context menu, selecting 'Cascade' or 'Tile' un-freezes it. So the bug seems to be oh-so-borderline sensitive to over-sized geometry. To within a few pixels. Maybe explains why it seems to work in some conditions (say, with Oxygen) but not others. > Will investigate > > Will investigate also method B.
