I'm working with a third-party developing a courseware development
application.
They're having trouble providing "backing store" for more than
one window. Keeping a pixmap for each window exhausts memory.
Can anyone provide a pointer for how to handle this?

In what way exhausts memory? Do they get a pixmap allocation failure, or do they get a server death? The server death problem is mentioned just a few notes back (2860?? I answered it today). If it is an alloc problem on a VMS server, it is probably the case that they are getting a single pixmap which is too big. (There is a limit of about one screenful for *each* pixmap on non-SPX color). In that case, you have to either do without, or change the code to get several pixmaps. Burns | |||||

What are you attempting to restore in those windows?
Restoring text might be more cheaply restored by just
redrawing it from memory on exposure..
