Hi again.

Just wondered if Oliver was still around who I think wrote the backend. 

As an iterim solution, I've gone back to SuSE 8.1 on the client where the 
scanner is and all is well. I'd just like all our clients to have the same OS 
for system consitency.

Is there anyone from SuSE still on this list who could help me get the scanner 
going under 8.2?

Thanks for your time and sorry to be such a pain as usual.
