ah, that helped. I thought Enlightenment would only draw a titlebar when
the title contains a string, but I was wrong :) thanx.

the virtual desktop is part of my window-manager and has no possibility to
configure this :(

yepp, I think so, too. I'd really like to see this option in the next
release *grin* :) the viewer is the one who transfers the data, and should
cache it, not the displaying server imho ... any events sent to the viewer
aren't regarded while the display is polled, so I couldn't even chance the
screen and close the viewer if I'd want to ... I had to wait until the
complete screen was transferred again :(
