SL2 Seekbar Glitch
I've worked with lots of modules over the years, but I've never seen this one. On some slides in a current SL2 module, I'm seeing the seekbar do this (both Web and LMS output):
There is no rhyme or reason, except for the fact that it may only show on slides which I've disabled/hidden the Next button on (for all the good it does, since it still shows even when hidden). I haven't checked all of those slides, but it looks like it may be the case, and shouldn't have anything to do with this weirdness.
