I'm the correspondent Rob refers to below ...
I've now tried a remote Debian box (instead of Solaris) for the display,
& again get a mottled pixmap. Also, I've made the icon toggle between this
& another icon when clicked, & the mottling is different each time.
Hope this stimulates someone,
Thanks,
Brian Keck
