Mouse arrow cursor will turn into a crosshair and desktop frozen

[Scott(0)]

Hello.

I'll be using LL 1.06 or 1.08 .....

Please clarify. Are you using LL 106, 108 or both?

... the mouse arrow cursor will turn into a crosshair and the desktop will seem frozen.  I found that if I do Alt-Tab and cycle to any open window that fixes it and the arrow and normal operation is back

If there are no open windows to alt-tab to does the desktop still freeze? Does the freeze always happen at the same time/under the same conditions (can you reproduce the problem or is it random)? If you boot on a live CD is the problem present?
