Odd behavior with mouse on Dell M4400 laptop

Hello all,

I have a couple of issues that are currently happening to one of our M4400 laptops.  These issues started about a month ago, and are getting progressively worse.  I think they are related, as they both started happening at the same time.

Issue 1.  Clicking on the tabs in Google Chrome causes the tab to suddenly close.  We are not clicking on the X within the tab.  It starts intermittenly, and the only way we have discovered fixing the issue is a triple click on the scroll.  We have tried multiple mice, and if they do not have a scroll that can be clicked, we must reboot the machine.

Issue 2.  When docking or undocking the laptop, the mouse pointer moves around correctly, but the buttons are disabled, you can not drag a window, close a window, double click on an icon, minimize a window, or any other function requiring a mouse click.  The workaround we have here is a  CTRL-ALT-DEL then start Task Manager...voila, mouse buttons work again.

Any ideas?

    could it be malware?  then run a scan with your updated AV, followed by mbam :

    Thanks for the response, I doubt it is malware.  Over the weekend wiped and reinstalled Windows 7, and the problem returned.  It now happens any time the laptop is undocked.  Rebooting does not fix it.

    *UPDATE - I may have found the culprit.  I recently uninstalled Google Talk, and the problem has yet to return.  Unfortunately, the engineers use Google Talk to communicate within the office.

    Final update:

    I contacted Dell support, and they were equally dumbfounded by this odd behavior.  Through a remote connection, I was able to reproduce the problem for them, but they had no answers.  They agreed to replace the laptop as it was under warranty.

    I also can confirm that GoogleTalk was not responsible as earlier thought.  One interesting note, we were able to remedy the issue by clicking on the middle scroll button on the USB connected mouse, however clicking the middle button on the trackpad was ineffective.  We agreed that there must be a conflict with the driver between the mouse and trackpad.
