Do you really simply say "zg" and look?
At our new DRX500 I'm facing the problem, that I start with "zg" and
then keep my hand from the keyboard and everything works fine. If I
start with "zg" and switch to aquisition
window, while the system reports to start all these fancy units (RCU,
TCU etc.) I get several errors. Depending on the microsecond when
clicking on the aquisition menu button, the system says "Connect
refused" but starts to collect data nevertheless - or it says
"Connect refused" and does nothing. Then I have to kill the "zg"-job
by hand.
But this silly behaviour it easily avoided by waiting for the message
"aquisition started". Then you can switch to aq-window without
danger.
