Well, although it was happening repeatedly in the session I was in, I can't get that exact problem to repeat. However, I have had the same symptom several times from a different action - resizing the pane. This isn't consistent but I've had it in several MM sessions (not yet in 1453 - you're too fast for me to keep up!). I eventually managed to get a Jing video yesterday, but it hung while 'finalising' (just my luck!), although it seems to be there now I've killed that process. Unfortunately it's not until the very end of a 5 minute video - hope you can skip http://www.screencast.com/t/l2e8PmtRz

Can you see that the scroll bar looks a little bigger in the first (error), but both say 228 files. The first is only showing 171 files.
