I updated to Crossover Games 7.2 yesterday and started up my saved games on Half Life 2 and it consistently crashes to the Steam app after about 10 minutes of playtime. Nothing obvious going on, game just freezes, shuts down and I am returned to my Steam account "My Games" page. I can restart it and play it again for another 10 minutes without any problems.
Am likely to downgrade to 7.1 so I can continue to play (didn't see any big changes for this game between 7.1 and 7.2) - just wondering if I am the only one running into this or if it is more widespread
