Steve - from what you describe, it sounds to me like all the CPU power is being used up in other intensive tasks, and so moving the cursor round becomes a task that gets the remnant of CPU power. This would make it jumpy. It would be this, if your configuration was low on memory and CPU speed. If you start up your 'book and have almost no active tasks, and your cursor/trackpad is still acting like this, then it is something else. A few experiments should identify the specific nature of the problem, and then you are hal;f way to getting a solution or explanation. regards, Trevor
