Even weirder is that I posted this query the other day but it seems to have disappeared. Ah well, maybe I posted it another forum in error?
I create a new document but when I try to type in the main window or paste copy into it, the window doesn't respond. Nothing hapens. The only solution is to close that window and open a new one which works just fine.
BTW, OSX 10.9.2, ME 3.6.4
