Uh... Thanks :lol: [shuffles away: Svn. :shock: Scary. :cry:] I, uh, solved it for now by editing ImagingTypes.pas and adding to my program:
[pascal] procedure StartVampyre;
begin
if sizeof(tvyimage) <> sizeof (timagedata)
then Die('Record size mismatch, check compiler options/conditionals.'#13#10
+ 'SizeOf(TVyImage) = %0; SizeOf(TImageData) = %1.'
, [sizeof(tvyimage), sizeof(timagedata)]);
end; [/pascal]

I'll... check it with the next version you release, ok? ops:
