I have compiled nedit 5.5 with openmotif 2.3 beta,
which ships as standard on OpenSUSE 10.2
libXm.so.4
Nedit is a great example of old and tested code, which works without
problems on older versions of Motif. So any problems must be caused
by OpenMotif, not by nedit source.
If I try to open a file, file selection box spits out thousands of

Ignoring Xlib error error code 2 request code 91

This is the full nedit info

Can some OM developer please download and compile nedit,
and check this out. If "simple" text editor like nedit has
trouble, then other applications will also break.

By the way, I am using compiz.
Same application statically linked against older motif works OK.
