I've searched & searched, and not found a single report of this, though I've experienced it on two different Dell laptops. Please note, this is -not- the issue where the mouse cursor jumps to a different part of the screen on its own. I run XP/SP3 with the taskbar set to show each window, not grouped by type, so I might easily have 20 or more items showing on the taskbar on multiple rows, but with only one row displayed. Then I scroll (since I only show a single row) from one row to the next, if I want to switch from one program to another & the program is not visible in the taskbar row showing. It's an old habit, and always worked in the past, with the exception of two different Dell laptops (but also works fine on other Dell laptops.) Unfortunately, the problem resolved on the first Dell laptop at some point, and I don't recall or know how or when. But I'm stuck with it on the second laptop. Specific behavior is: When I have multiple program windows showing on the taskbar, with multple rows, sometimes I click on one to restore it, and instead a completely different window restores. This happens no matter how carefully, slowly, or un-quickly I click on it. At the same time, the task bar will scroll on its own to the row for the window that opens, so apparently it "knows" what window it's opening, but it's not the one I selected with the mouse. The mouse pointer is not set to jump to the most likely item; I hate that behavior. I have updated both the mouse (well, it's a touchpad actually) and display drivers. However, because the scroll bar actually seems to select another row when I click, not just the wrong window, I think something else is at play. If it's relevant, both laptops have a wide-screen format that I run at 1280x768 or 1280x800. The really bizarre thing about this behavior is that it happens with every-other selection; that is, it happens precisely one time out of every 2 that I'll click on the taskbar to restore a window. The other click will restore the window I really select. It doesn't seem to confine itself to any particular program or circumstances. Having experienced this on two different laptops, I feel sure I'm not the only person in the world with the problem, although I know the preference to run a bunch of separate windows showing on the taskbar (instead of grouping them) is not the common one. Anybody have any thoughts on how to fix this, rather than "do things differently"? I've tried to search for answers in every way I can imagine, but all I come up with are the (frequent) issues have with jumping mouse on Dell laptops, which is a completely different issue (and one I'm familiar with.) Thanks.
