I'll note in passing that custom images appears to confuse the heck out of the code that does the little head "headshot available" icons. I find that switching from my test profile to another and then back results in an almost random (well, apparently random, I'm sure it's deterministic) display of which actor has headshots, although selecting them gives the expected results.

Most likely due to disk/memory cacheing. If there is no interrupt, sometimes a program only sees what is in a memory buffer untiil an explicit re-read of the disk is forced.
