Hi,
I was looking for the option to prevent the explorer windows from popping up when I mouse over them when all of a sudden no more text was being rendered in the right hand preferences pane. Just sand colored horizontal bars. This probably happened around the 'explorer window font' property tab but I'm not sure. I tried two tabs and both behaved the same (no text). I clicked in the right hand pane hoping to make text appear but that's when PI crashed. I haven't reproduced this yet. After restarting PI shows all preferences fine.
Just mentioning this in case someone else runs into it.
Vista x64, latest PI.
