Hi Kevin
I've just moved this to Website Help. Jason (KG Admin) is on holiday for a couple of weeks (although he'll no doubt be peeking in from time to time

). Anyway, by moving your question here, he's more chance of seeing this and maybe helping you.
Personally I've had no problems at all recently, although I do get logged out somehow from time to time. A stupid question, but I have to ask, you are ticking the box which says to log you automatically in each time?
