One thing you might consider is using a custom property; set the
ItzInvisible of the stack to false when the fading starts, and set it to true
when the
fading is done.
Another thing you might try is moving your "doFadeIn 0" statement to the
"doFadeOut" handler, like so:
on doFadeOut r
set the width of me to r
set the height of me to r
if r =0 then
doFadeIn 0
else
send "doFadeOut r-1" to me in 1 tick
end if
end doFadeOut
You shouldn't need to explicitly exit "doFadeOut"; the way this is set up,
it simply won't send "doFadeOut" when R = 0, which means the "send"-loop
*will* finish at that point.
Hope this helps...
