For a long time after changing the video settings, I've been stuck in fullscreen mode every time I open ADOM. When I change it to windowed mode, the window lies on the top-left corner of the screen with the titlebar hidden. After I right-clicked the taskbar and pressed "Cascade windows" in the context menu, the game becomes unresponsive. The lightning animation still happens at the main menu, but I can't do anything else.
