I find flanker a lot less stable than it ever used to be and its the 2.5 patch thats causeing the problem. OK, no great revelation there but why is it so poor? So far, I've had crash to black screen, total lockup and reboots. This usually occurs in the mission editor especially with the new missions. Flanker was the most stable sim I had until now and it vexes me in no small way. Could go back to 2.3, but would miss the improvements too much. Oh well, hope the guys at eagle come up with a cure soon.
