I have a Sony laptop and never experienced this until this past 
week.  I use both a USB mouse and USB keyboard and have found that 
the disappearing mouse problem only surfaces when I plug the mouse 
into the USB bus available on keyboard.  If I plug both the mouse 
and keyboard directly into laptop the problem doesn't occur.  I 
suspect some piece of software has been changed recently but 
haven't had the time to try and track it down.

Logitech Keyboard: Y-BC9
Logitech Wheel Mouse: M-BE58
