Hi, I too am experiencing weirdness with fades. Crossfades, for example,work but are no longer shown at the crossfade point. Instead they show up about a bar further back (which can be confusing). Additionaly, I'm getting an error message when I insert fade ins and outs. (Not at home at the mo, so can't say what message it is.) The fades work but I have to click a couple of times on a box which blatthers on about permissions. I never had this problem with logic pro 6 (I upgraded to 7 just before 8 came out,doh!).
Would also be very grateful if somebody could say why this is happenig.
