Problem Details:

I recently just got a secondary monitor and run it on dual monitors under Windows 8.1

Since getting that monitor, osu! refuses to play in fullscreen. The fullscreen option is ticked but it is actually running in fullscreen borderless.

I can infer that it is running in borderless because if you try to change the Windows system volume using a shortcut, the volume HUD will show.



I tested this by putting osu! on a laptop running Windows 8.1 and putting osu! fullscreen; the volume HUD did not show. The volume HUD only showed on the PC with dual monitors.

Also, skype call notifications now appear when osu! is "fullscreen" on dual monitors. This does not happen on the laptop, only on dual monitors.



osu! version: 20140814.1 (latest)
