Does anyone else have problems with mt4 lagging? For some reason periodically during my trading day, mt4 starts to freeze and lag? I thought it was my broker so i signed up to a different mt4 broker just for charting but this is the third time its started happening. Im also running oanda and sometimes fxcm but there is nothing running in the background like msn messenger or skype etc. Just my charts and the odd webpage like forexfactory. I have 4 gig ram and 64 bit OS. Any ideas?
