Fullscreen mode and "Optimal Resolution Notificaiton" on Windows

When I run my app in FullScreen mode on Windows, I get the Optimal Resolution notification from the Windows tray, complaining that I made a poor choice of screen resolutions. This pulls focus away from the game window. I’ve tried this on a few different Windows machine and different versions of Windows, and have seen the same thing. Professional apps seem to be able switch the actual screen resolution and avoid this popup.

I don’t think I’m doing anything special for my mode selection. Am I missing something? I would have thought someone else would posted about this if it wasn’t just me, so I assume I’m doing something wrong… ?? I know WindowedFullScreen won’t have this problem, but I have other problems with WindowedFullScreen…

Anyway, have other people run in to this?
