Thank you Andrew,

but:
Isn't plend only be called upon destruction of plstream?
And I call the plspause(0).
Actually I found a way to let the xwin driver to handle the
events via plcmd.
I works fine now, but how can I be sure that the driver
will NOT handle the events implicit?
What about SetOpt( "drvopt","usepth=0") ?

Thats very valueable information. Now I understand why
the pthreads seem to do nothing on my system.
SetOpt( "drvopt","usepth=0") will disable pthreads
on all systems, even another user has compiled it with
pthreads?
Using this option, do I need to include pthreads in my
program?

thanks,
