Thanks for the answer - I know the problem is far beyond the standard 
user's problem :(.

Sure. 5 letter acronyms are evil - I tend to mix the letters up.

Terminal Server is debian 4
Client is debian 5
No other application seem to have problems - this is the reason why I tried 
OOo mailing list first.

It's a local gigabit network - no bandwidth problems known. While the 
OOo "No redraw condition" other applications work without problems. The 
problem does not vanish by its own - you have to close all OOo windows and 
start again to end it.

The clients have 1G main memory - there should be no problem, but I try to 
verify with xrestop while the NRC (no redraw contidion) occurs. Thanks for 
the input - I did not check that so far.

Did already a NX session - I could not trigger the NRC so far - which does 
not prove anything. This is so frustrating about the NRC: there is no 
positive proof...

Using kdm as display manager here - but yes, it may help. It has be some 
time since I read it.

Is there any way to get some useful logging out of xorg and OOo? xorg does 
no timestamps in the .xsession-errors and I found no OOo logging at all so 
far. Maybe some of the environment variables from 
http://wiki.services.openoffice.org/wiki/Environment_Variables
may help.
