Probably unconnected but when I popped into the site over the weekend, using my woman's PC, anything I typed into the reply box was as slow as anything, and it had often slung typing when it finally finished putting it up on the screen so I had to go back and edit. Other websites were fine though. Not had the problem on my PC.
Her PC is both old and new. It was upgraded not that long ago although the same motherboard/processor remains. It is possible it s connected to some graphics problem we know exists, but was strange it seemed to affect this site alone.
