I just upgraded to AE CS4. One thing that's weird is whenever I have a bunch of layer's animated parameters viewable (u), if I enable Time Remapping on a different layer, all the other layers open parameters are hidden/collapsed. I am forced to select the layers and hit u again. I dunno if it happens with anything else. Hitting p,s,t,r doesn't hide the other layers contents; just seems like enabling timeremapping....
Anyone else experienced that? Setting somewhere? Should I submit bug report?
PS. So glad to see that duplicating layers updates the parent to the new duplicate. I've asked for that for a while, so THANK YOU!
Not that I'm aware of. Sounds like something specific on your machine. The only time when I had this happen is, if you enable TR on multiple layers that have different property states revealed, but even that's a bug IMO (an unimportant one, though). What OS are you on? Anything out of the ordinary on your timeline (other temporal effects perhaps)?
