Can I alter the frame rate of an animated GIF by script?

[Graham Samuel]

Folks, I'm struggling with animated GIFs again - they can behave strangely 
in earlier versions of Windows (like ME); and even with Windos XP, 
sometimes starting one animation (showing in a button with the GIF as an 
icon) can stop an animation already running in another button... anyway I'm 
trying all sorts of workarounds to these problems, and it occurs to me that 
I could reduce the number of animated GIFs in my app (which might be a 
cause of these difficulties) if I could change the frame rate of an 
animated GIF on the fly. So far I haven't found anything in the 
documentation about this: can anyone say if it's possible and if so, how to 
do it?

TIA

Graham
