I finished my flash logo for work and am now having a problem when trying to publish/export/play the file. On frame 110 when the first shimmer crosses the "M" I get a hiccup on that frame, it should be a smooth transition. Once the video plays once the replay works fine, but this is going to be the intro to our website, one time view.

The playback was working great the day before. Today, after some more tweeks, not so good. Only thing I could fathom was maybe too many masks (added 1 more today, 3 in total) were being applied but I tried removing all masks and am still having the same problem. Any ideas as to what is causing this?
