Hi! I'm testing Sibelius 7 in the Developer Preview (so not a final version) of OS X Mavericks. A lot of things are running very smoothly, but there is one rather huge problem: no other windows except the main window, will show. So no mixer, keypad, even engraving rules or house styles. If I open house styles, for example, the menu bar of the main score window will turn white, indicating it is not the active window anymore, but I don't see the house style window. If I press return, then, the first house style is selected (I can see the formatting change), so I think the window must be somewhere, but it's just not visible.
Can anyone think of a fix for this? Or is this just one of the bugs that will have to be fixed by the Sibelius developers?
Thank you very much in advance!
