Hey! I just ran into this exact same issue! Our receptionist has this randomly happening on her XP Pro machine. I looked at it while it was happening, hoping to find a quick fix, and I wasn't able to find an obvious reason for it. She's using a Microsoft wheel-mouse (white 2 button model with grey scroll-wheel in the middle, and a red plastic bottom with optical red LED). I checked under the Mouse settings in the Control Panel for anything out of the ordinary, but everything seemed to be set to defaults. There is a "click lock" feature you can check-mark to enable, which I thought was a potential issue - but it wasn't turned on.
After messing around with everything and clicking things randomly, the problem suddenly went away again.
This seems like a software bug of some sort to me. But in our case, it's sure going to be tough to track down. She has at least 6 or 7 applications open at the same time, including ACCPAC Accounting software for Windows, "Access It! Ultra" (security software that manages our security gate and ID cards in the company), Microsoft Word, Outlook, and so on.
Hope someone else can shed some light on this?
I have an intermittent problem that causes a left click on my mouse to highlight not only the item I'm trying to select but everything below the selected item. For instance, clicking on a link on a web page causes the whole page below the link to become selected as if I was selecting the whole area. This happens across all programs when it happens including Explorer, Outlook, or anything where a selection can be made which leads me to believe it is an XP problem. The only way to resolve the problem is to reboot.
I'm running XP Pro SP2 on a 3.4 P4 with 1 Gig of memory. This is a fresh install of XP on a new SATA drive but the problem occurred before this install as well. I thought the new install would cure it.
Anyone recognize this problem?
