I've been in PB 5 years and have experienced game crashes occasionally throughout that time. I had two or three within a short period a couple months ago. The circumstances of these last crashes were very similar to those described above by Jon and JLF. A game requiring a lot of pitching/player changes in a short period and always occurring when I click on a player to see his stats. What always happens to me is an error message pops up saying in effect the program has performed an illegal operation and will be shut down.
