"Edit Style" dialog not displaying correctly - nightly build R4156 on Mac OS X 10.6.7
After opening Style > Edit General Style and changing to any item in the list in the left hand pane, the right hand pane becomes empty (white).
Moving the cursor over the white area causes the fields to be displayed but not their labels.
Changing focus to another running application and then back to MuseScore results in correct display until the item in the list is changed again.
Images attached for clarity.
