If your working with Virtual PC it may happen that your mouse cursor disappears when you move it over an input field.

In the picture below the cursor is directly positioned over the password input field...

If you want to have your cursor back you can try one of the following options:

1. Start -> Control Panel -> Mouse -> Pointers -> Change cursor scheme to „Windows Black Scheme“

2. Right-click on the desktop, select Properties -> Select the Settings tab -> Press Advanced -> Press Troubleshoot -> Set the Hardware Acceleration slider to one step less than Full -> Press Apply and OK

(not recommended because your cursor can start studdering)

3. Replacing the „beam“ cursors in „c:\windows\cursors“ with the one from Vista

(didn’t work for me)
