Hello, Just bought a new pc with win xp. (been using win 98 for years before). I use IB's TWS with win 98 with no problems, but with win xp and TWS running, my mouse get very jerky, not smooth movement. If I close TWS, the mouse works fine, so I think there is some conflict with TWS. Doesn't happen with win 98 at all. Anyone have the same problem or possibly offer any tips. Thanks in advance.
