Thanks for that advice, before the problem I was monitoring 4 markets at once on four profiles at 1 sec refresh rate and everything was fine, have tried to change to 2 sec refresh rate, as you say I will try cutting down the profiles etc to see if it helps, I don't use the market locator.I had to use trial and error with ver 7 but got it right in the end.Just find it strange that it worked fine for ages and now doesnt and I definitely haven't made any setting changes.
