For some reason, your GIF images seem to be broken. Could you send them to
me privately (possibly within a Zip file or something similar).

I have no explanation yet. We'll need to recompile the old betas and do some
pretty dirty work to find the reasons.. this could come from different 
fixed-point routines to some change we've made to the TrueType interpreter.

I must admit I don't have the TT interpreter enabled in most builds I do..
