Hugh,
Does it make more sense to add:
on mouseUp
if GrabMe is true then set GrabMe to false
pass mouseUp
end if
on mouseRelease
mouseUp
pass mouseRelease
end mouseRelease
rather than checking for the mouseUp state in the mouseMove handler?
That way you are 'constantly polling' mouseUp.
Just my 2 cents...
best,
Chipp

if the mouse is "up" then
