Window Options

Keep the DMD window in front of the backglass window: If this box is checked, PinballY will make sure that its DMD window is always displayed in front of the backglass window. Even if you click the mouse on the backglass window, the DMD window will still stay in front of it. By default (if the box isn't checked), the DMD window follows the normal Windows UI rules where you can bring other windows in front of it by clicking on them, and you can bring the DMD window back in front by clicking on it.

This option might be handy if you're using a single-monitor or two-monitor setup and you're positioning both the backglass and DMD on the same monitor. (In the more typical pin cab setup, where you have three separate monitors - playfield, backglass, and DMD - the respective layering of these windows is kind of irrelevant since the windows are all on separate monitors anyway.)

Note that this option only affects the PinballY DMD window and backglass window. It doesn't have any effect on DMD windows displayed by other programs, such as the "virtual DMD" window in Freezy's dmd-extensions system, or the VPinMAME DMD window that appears while you're playing a Visual Pinball game, or the B2S Backglass Server DMD window that might also appear while a VP game is running. It also doesn't affect the layering of backglass windows from other programs, such as the B2S Backglass Server window.
