Problem(s) Encountered:

After aborting a focusing script in prospero, no more data acquisition was possible. An error saying that  Data Acquisition was already in progress  appeared.

Did a restart of Prospero and Caliban, new error appeared when restarting Prospero saying  Caliban & IC disks are not synched.

Did a complete restart of the observing workstation, but the problem still persisted and  -SYNC  was red in Prospero Status window.

Solutions:

We referred to the IC-to-Caliban Transfer Disk error recovery procedure. We then proceeded with a cold reboot of the IC, after figuring out which keyboard it was connected to. After the IC restart and restart of the workstation, Prospero was able to be started properly and data acquisition was possible. The only lingering effect is the lack of some graphics in the Prospero Status window.
