2 days ago I have noticed while playing Runescape my mouse is all over the place behaving rather odd. The lag is still bad now my mouse? Is anyone else experiencing this also? I am getting very frustrated with the game now. Enough is enough. Here is my computer information: System: Dell Processor: Intel Pentium 4 CPU 3.00GHz Memory: 3062MB RAM BIOS: Phoenix ROM BIOS PLUS Version 1.10 A03 Page File: 426MB used, 4011MB Available Operating System: Microsoft Windows XP Professional (5.1, Build 2600) System Model: OptPlex GX 280 DirectX version 9.0c Java Version: 6 Update 31 Mouse: Logitech Optical HD compliant mouse I also took my mouse apart which is 2 months old and cleaned it it is optical still no change this is only happening on Runescape. Any help would be greatly appreciated.
