I haven't found anywhere where this bug would effect LFB - you don't seem to make use of the old backdrop after freezing? (But it does make the VC demo, and to some extent Frasse, look strange.)
I decided to use 2.0.1 for the official Life Flashes By release instead of 2.1, so no huge rush here.
Oh? May I ask why? Did you find anything else that's wrong in the new version, or did you simply suspect that I hadn't tested it enough before release this time? The Alt+Tab bug is nice to be rid of. (And the related tablet issue, but I suspect that the number of pen users is pretty low.)
