Problem with File ... Open ... Menu Item in MuseScore 1.3 on Mavericks
I am using MuseScore 1.3 on a one-year-old MacBook Pro with Mac OS X 10.9 (Mavericks).
Since I have been using Mavericks, the File / Open menu does not work any more. When I click on File / Open, the file picker shows up for about one second and then disappers. From then on all menu items in the File menu are disabled (grayed out) until I terminate MuseScore and restart it again.
Note however, that the File / Open recent menu item still works and also double-clicking on a MuseScore file (when MuseScore is inactive) starts MuseScore with the requested file correctly (this is my work-aound for the unusable Fil / Open menu).
Thanks for any help!
