Hey,
I use bblean on a laptop and when i am viewing a page that allows the user to scroll, i use my handy side vertical scroller on my keyboard. however, when i begin to slide down the page, on the desktop background and sometimes on the very page im on, blocks of desktop background image go away or even sometimes mimic the text that i am scrolling by. This is odd and have restarted blackbox.exe several times but the probably keeps coming back.

Let me know if there are any solutions. Thanks

Sounds like a driver problem or something to do with your specific hardware\Windows version. Giving that information would be helpful.
