You can't change the frameRate but you don't need to rely on it either. Set
the repeatCount of your GIF to 0 and increment the currentFrame via script.
[example card script]
get the currentFrame of img myGIF
if it < the frameCount of img myGIF then
put it+1 into F
else put 1 into F
set the currentFrame of img myGIF to F
send "playGIF" to me in 100 milliseconds #10 FPS
See the list archives for more on this technique. A scripted solution gives
you much greater control over GIF playback than the built-in timing in
