Hi Wolf and group.
The grabber does indeed use Spectrum Lab's http server, and I have already 
slowed the java refresh down to 5 seconds. I am watching the data 
throughput, and it seems that the system can cope with 2 simultaneous high 
refresh connections, but 3rd starts generating errors, including access 
violations on the server.
The use of the non java page reduces the bandwidth noticeably, but the 
refresh on that is only 30 sec. Still good enough to not miss anything.
I may put the java version out to 10 sec refresh later to see what happens.
Thanks for the comments
Regards
mark GM4ISM
