I apologise if this is inappropriate, but I am having trouble saving GIMP images in Windows 98, prior to changing over to Linux - and here seems the best source of nous.
Having aquired with TWAIN, each time I try one of the SAVE methods, for any IMAGE TYPE, I get the message :-
"PANGO Warning (recursed) ** couldnt load font "MS Sans Serif 10" falling back to "Sans 10" aborting"
and GIMP shuts down completely.
I believe that GIMP is compatible with Windows, although it is a Linux program - and it installed OK.
