I'm guessing the icon issue is not easily fixable. AFAIR, DOpus expects data from icon.library in a format different to that which MorphOS icon.library supplies.

Probably what will have to be done (if it hasn't already), is something like removing all icon.library calls and replacing with code to manually decode PNG, newicon, Amiga icons and glow icons and pass them in a format that DOpus is compatible with.

Or, probably a lot more work, to completely re-write DOpus icon handling so it can handle whatever MorphOS icon.library is throwing at it.

Been a really, really long time since I talked to MorphOS devs about DOpus so my knowledge may be very out of date.
