I've just compiled the latest svn and tested the Black Glass skin on it. This issue shows up in every screen that has an actiongroup control inside (almost every file!). This is because i inserted a dummy image to obtain the sliding in/out animations of the left menu and that was working for MP 1.1.0. Now that the animations management code of Mediaportal is ok, the dummy image is not needed anymore and causes the issue. I've started patching the skin and today i'm going to slowly upload the fixed files on Google Code Black Glass Svn in a new folder for Mediaportal 1.2.0 only (look for the "Black Glass for Mediaportal 1.2.0" folder).
Could you also do this for Black Glass Nova?
