In reply to MM0FMF:
there have only been 3 occasions I can find when you have logged on and then logged on again within 10mins.
Some of the timeouts have definitely been when I have been extracting data for the Summitsbase 70cms report and I probably haven’t bothered logging in again straight away on those occasions. Even if this takes the odds nearer 1 in 80 or even 1 in 70, that’s pretty good going by my reckoning. Nowt to fix I’d say.
