I am not brilliant at computers but I am teachable!
Twice now with a VASSAL upgrade, the computer makes me an observer in an ongoing game and I can not see my cards or play. I play Pursuit of Glory, 1H version - the oldest and has least glitches.
New MAC, Java 1.6.0_26 from Apple, Vassal 3.1.15 - downloading .16 is when the problem occurred.
I ended up going in with the same password to play a new game. Thoughts?
