vm/png/mime/windows/xemacs type problem

On windows xemacs (21.1.13) running on cygwin, when I get a email picture (like png) I get 'Unknown/Bad PNG image encoding' when I try to view the picture in VM. If I save the attachment to a file I can view the picture, so the attachment was ok. I tracked the error message down to vm-mime-display-internal-image-xemacs-xxxx The function created a png glyph with the contents of the picture stored in c:/windows/TEMP/vm1. When I tried to view c:/windows/TEMP/vm1, I get an image-conversion error shown below. So, I'm a little lost as to what to try now. -jeff ---- 1 -> vm-mime-display-internal-image-xemacs-xxxx: layout=[("image/png") ("image/png") "base64" nil "XEmacs screen shot" ("inline" "filename=xemacs2.png") ("inline" "filename=\"xemacs2.png\"") #<marker at 2152624 in INBOX 0x236067c> #<marker at 2152775 in INBOX 0x2360664> #<marker at 2152776 in INBOX 0x236055c> #<marker at 2170916 in INBOX 0x2360544> nil ((vm-mime-display-internal-image-xxxx . #<glyph (buffer) #<image-specifier global=(((mswindows win) .
