I want my game to remain in full screen and alt-tab (or disable it) safely. At the moment, alt-tab or some other window that pops up will crash the game. Would I need to do something (disable dxtimer ?) in the form losing focus event? What other "safe" things should I do to preserve the state etc?

As I have never used DelphiX, I do not know any specifics of getting it to handle task-switching. When using DirectX (DirectDraw or Direct3D), you have to handle the possibilities of surfaces and devices being lost. These surfaces then have to be restored and the devices reset before they can be used again.
