I have my desktop icons hidden and use the Desktop on my lower right corner of the task bar. When I click to scroll down searching for a particular item, the scrolling freezes the further down I go. It takes a minute or more to unfreeze and continue to scroll , then it stops again. What can be the problem.
How much memory & disk free space do you have ?
Bring up task manager, click on resource tab, then see what is hogging your CPU cycles when you scroll.....
