I, too, have had the exact same problem almost, only it stops working while I am in play-by-play mode, and click on either teams' lineup tabs or the OOTP Broadcast tab. I can no longer control substitutions in games, for when I click on my team's tab, it freezes up. This is a game that I have played out every single game over the past 3 versions of OOTP, and am in my 5th season. Went from being a Rookie league manager, and am now a AAA manager, and was hoping to make it to the majors at the end of my current season, but alas, I may have to start ALL OVER!
