I have to say that these last days it was really problematic. It's always crashing, sometimes a few minutes after I open or reopen axe edit. I had to shut down the axe fx maybe ten times during one hour of playing. I may be wrong but it seems to be more present when used in conjunction with cab lab. Yesterday I played a few hours with AxeEdit only and had no problem. But on the other hand there was less "tweaking" involved.
