When we first installed R4 on our Suns and CONVEXen, we still had a few systems running R3 servers. For the most part, we did not see any problems, but 
occasionally strange things did happen. Most of the problems seem related to
R3 window managers and not the server. For example, an R4 xterm would not
size properly on an R3 window manager. The xterm window would come up
8x4 or some random, tiny size.

Right now we use several old R3 servers on HPs and old Tek X terminals.
Everything works ok, except for shape extensions and multi-buffering.
Beware R3 window managers and R4 Xt applications.
