Not sure whether this should be in Module Support or here... but the problem only arose when I updated to VASSAL 3.2.2. I am using the Twilight-Struggle-Deluxe-3.0.10a module. There is a Card window that contains a button that automatically distributes the initial hands of cards. This button did not do anything in VASSAL 3.2.2. I reinstalled 3.1.19 (I forgot there had been a 3.1.20) and the intial card distribution worked fine.
I'm a little surprised that I seem to be the first to report this... something special with my Windows 7 Professional?
