Chronos or PAL Sample Control is 'hanging' when interrupting a schedule.

When Chronos or PAL Sample Control software is used and a running schedule is stopped it can be that the software goes into a 'hanging' situation.
When using the LINEX 'Overlapped" must be unchecked:
 
chronos and linex
 
 
Or to overcome this it is advised to check the checkbox Run error method. (this box will come up when Stop button is pressed)
