IDL Display under RH7 [message #23446]

In attempting to display plots in IDL running under Red Hat 7.0 (KDE),
the plot comes up in the standard IDL graphics window, but if any of the
other windows overlap with it, the part of the IDL window that was
overlaped is erased. When the IDL window is brought up to the front, it
doesn't redraw the figure but insted it remains blank.

Maybe I should be posting this to a Linux (or KDE) newsgroup, but if
anyone has any idea how to fix this (or it is a known IDL problem),
please let me know.

Hugh

[backing store problem]

Your other option is to add

# IDL backing store
idl.retain: 2

to your .Xresources file. It has the same effect as the other solutions
and applies to all idl windows.

My first suggestion is to look up Backing Store in the IDL Help. And my
apologies if you've already set this parameter.
