I think it might have to do with PlayerMenu - I tried out the patch posted and I got it, too - and "PMEM_Frame_Button" appears prominently in the ExtMenu.xml file.
thx !! - think u hit it
damn, totally forgot that i switched back to palyermenue today instead of palyerlinkmenue. And funny thing is, i did a full string search but somehow i didnt get a result, seems i was a bit sleepy there.
