Need some hints as to what to look at here. As I mouse over a component I have set a custom cursor using CursorManager.setCursor(..).
I am gradully moving the mouse up the screen over the face of the component, there is no further cursor code interaction. As the mouse continues to move up the cursor suddenly jumps 200px up the page and as I move a bit further it equally suddenly jumps back down the page to where it "really should be". It is jumping when the "target" changes, it seems like it jumps to the top of the new target which is behind the original target but why? I am not so concerned about why it pick up the background element that I understand but I am concerned about why the mouse position changes. I am just gradually moving my mouse up the screen, as I mouse over something it shouldn't alter the mouse position should it, so why should the cursor jump around? Could this be affected by tooltips, does displaying a tooltip cause the cursor position to change? tks
