Hi-

I have read the messages regarding this problem with interest 
because I have NOT seen it here with the Facscan we have had for 
4+ years.

It would seem improbable that power line problems at different 
institutions would affect just the SSC. I would suspect that the 
problem is more fundamental.

We do not use a BD computer system for data collection or 
instrument control. Having built our own system it is relevant 
to note that we found the computer interface on our Facscan to 
have a very shaky design. When updating some instrument 
parameters, other ones change without reason, so our control 
routines have to be very carefully done. Since data and 
instrument control are handled through the same interface, that 
would be a place to focus on. In particular, it would be 
relevant to see if certain configurations and data rates cause 
this problem, while others do not.
