hi CK (and everybody)
- The culprit seems to be my external ISDN modem (I'll check out to see whether it
is actually the modem or the USB port). If the port is not connected, the system
idles at 0% - 2% CPU, if connected, it shoots up to around 75%. (By the way, in response
to your question, no other processes show CPU usage other than zero).
I have a "Duxbury" 128000 BPS ISDN TA modem. I wonder if anybody else is also experiencing
a problem like this. While the problem has not been solved yet, at least I know now
that I can have proper performance if I boot up without my modem.
CK thanks for your time spent on advice.
