1. In the case of a display problem: Perhaps the grabber has stalled. Try clicking on 'restart grabber' - then confirm.
2. The Wapps may be acting up: go to CIMA and click on 'pulsar observing mode' - then 'more' - then 'restart wapps'
(you may need to 'restart grabber' on the alfamonitor window).
3. Try logging out (and then back in) of CIMA entirely and restarting the observations..
4. Call the Friend of the observations.
