Bug in hm--html-minor-mode on NT

On trying to use this mode, I get the following error: Signaling: (error "Invalid image-instantiator format" autodetect) (from the backtrace). This is running xemacs-21.0 beta 66 on Win32, with the latest hm--html-mode package, and happens with --vanilla. This seems to be coming from the idd-make-drag-and-drop-pointer function, and it's not clear to me whether this is an NT bug (ie drag&drop isn't properly supported there), or a more general bug. Lisp stack is: Signaling: (error "Invalid image-instantiator format" autodetect) check-valid-instantiator([autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"] image) canonicalize-spec-list([autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"] image) set-specifier(#<image-specifier global=<unspecified> fallback=((nil . ...)) 0x12e0> [autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"] nil nil nil) set-glyph-property(#<glyph (pointer) #<image-specifier global=<unspecified> fallback=(...) 0x12e0>0x12df> image [autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"] nil nil nil) set-glyph-image(#<glyph (pointer) #<image-specifier global=<unspecified> fallback=(...) 0x12e0>0x12df> [autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"]) make-glyph([autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"] pointer) make-pointer-glyph([autodetect :data "c:\\Apps\\xemacs\\xemacs-21.0-current\\etc\\idd\\drop"]) idd-make-drag-and-drop-pointer-glyph() byte-code("..."
