Hi there, foks,
I've been burning along in AE CS6, loving it so far, although have discovered a couple quirks. Perhaps I'm doing something wrong. Hopefully somebody can let me know! 
1) I have set Resolution to AUTO but when I change to a different resolution the magnification doesn't automatically readjust. For example, I have resolution set to half and magification set to 50%. If I change the resolution to 25% magnification remains at 50% and it looks awful. I do not have Preserve Resolution checked in the compositions advanced settings. Is there some other place where I need to enable automatic shifting?
2) importing layered photoshop files that have consecutively numbered names creates chaos! For example, an artist supplied me with 5 photoshop files of painted cactuses. Each has 3 layers. They are named Cactus1, Cactus2, Cactus3, etc... When I import them, the first works, but all the others come in with only 4frm duration that can't be altered (I've set import durations to 30 seconds) and malfunction badly. When I change the names to CactusOne, CactusTwo, etc... everything imports correctly. Is this something new in AE, or some kind of bug?
Many thanks for your thoughts, folks!
