Okay, this one makes no sense at all. I found a bug that causes the
projector to advance 1 frame, causing a large number of scripts to fail,
because they're checking for the frameLabel. The weird part is the bug
occurs ONLY in Projector mode, and not Authoring. What I can't figure out
is why the frame is changing in the first place - there's no code anywhere
telling it to do that. All frame-related code either says "go the frame" or
it says to go to a specific marker, never "go the frame + 1" or "go next" or
anything like that. The other weird thing is it always seems to be
triggered by a right-click of the mouse. Anybody ever see anything like
this before?

Okay, after a bit of error-checking, I've discovered that this is caused by
the frame script NOT running sometimes, just for one frame. Thus, my script
saying:

on exitFrame
go the frame
end

is simply not happening for one frame, and the movie naturally advances to
the next frame. (The frame scripts are all stretched out to at least 5
frames, so the movie then holds on that next frame.) Now, WHY this script
is not occurring when the right mouse button is clicked utterly baffles me.
I've made a quick and ugly patch for the problem with the following code:

if the frame mod 5 > 0 and the frame > 1 then go the frame - (the frame mod
5)

This makes sure the frame always stays on a multiple of 5 (or frame 1, since
there isn't a frame 0), and even if it advances 1 frame for unknown reasons,
it will automatically jump back to the most recent multiple of 5. Since all
my markers are set at multiples of 5, this corrects the problem, but it
doesn't explain why the problem occurs in the first place. Also, this is
only a partial solution, as the movie will still be sitting on the wrong
frame for 1 frame - so far this doesn't cause any errors, but there's always
the possibility that a complication could occur. Moreover, I don't think I
should HAVE to fix the problem this way, the "go the frame" script by all
rights SHOULD execute every frame, but for whatever reason it doesn't, and
I'm forced to accomodate. Anybody have a clue what could be causing this?
