since you are barve enough to use CVS, you should also learn 
how to use "cvs update -D 'date'" or "cvs update -r 'revision'" 
to find when and why a problem started! There is some work 
going on in parallelism (task group impllementation in PW) right 
now. You can follow it on the web-cvs interface. The last changes 
were made this afternoon (Central Europe Time). If your problem 
is not fixed in the next few days, and if you have evidence that it 
is due to a bug in the code and not to a bug in anything else, please 
submit your problem again
