Over the past week my charts (FutureSource fXtra) and trading platform (Strategy Runner), on my desktop, have been lagging for about 5 to 20 seconds during major moves. I believe there is a problem with my XP setup, because these applications run without delay on my laptop using the same DSL router. I tried just about everything (reinstalled Windows XP, scanned for viruses & adware programs, and tried various XP optimization tools) to no avail. Any recommendations/solutions to fix this problem would be greatly appreciated. Thanks.
