I use flipbook out of peg a lot, and it seems in this version is not working properly. I installed the new version just now, on mac, and when drawing is out of peg it simply disappears, flipping works only when I click reset on the light table. Annoying. Will you fix it, please?
P.s. to be more precise in describing the bug - when one of the drawing is out of peg, not only it doesn't flip at all, but some strange behavior happens, such as layers which are hidden start to show, and problematic seems only the right side of light table (after drawings). Left ones reacts as it suppose to.
To confirm it is a bug I installed back the 10.5.3 and now it works as it suppose

good luck
Best,
