Mouse wierdness! Anyone experienced this?

Hi All
I just started moving my VB6 and my developed apps over to another
machine. For some reason, the mouse points and clicks fine... but the
scroll device doesn't work with VB6 development environment on this
machine! It's a standard Microsoft Wheel mouse, and works fine in all
other applications installed on that machine. I uninstalled the
driver, and replugged the mouse in the USB slot... It's still not
scrolling in the dev. env.
Any ideas?
Thanks
John
