+21.12.2011:
+        - Fixed some mixer issues: Very slow updating with large mixer when setting visible tracks for example: Set and check 
+           Style() object name in MusE::loadTheme() so that slow mixer ScrollArea::viewportEvent() is not called every time.  (Tim...)
+          Split strips and amixer into configChanged() and songChanged() handling. Do not fully rebuild mixers upon configChanged().
+          Fixed mixer windows raising above others, even briefly: Do not raise mixer windows in MusE::focusInEvent().
+        - Fixed bigtime leak: Not destroyed. Give it a parent in MusE::showBigtime().
 20.12.2011:
         - Litle break for some polish. Route button icons. Rebuild midi track info ui file - was 3 columns not 2. (Tim)
         * Fixed: Hopefully, finally: Non-appearing track info scroll bar.  (Tim)
