My overylay pop up windows scroll very slowly and lag. Can this be Fixed?

This is mostly a problem in the images file browser. Scrolling up and down through a few images is extremely lagging. But every overlay pop up menu in C5 has the same problem to a varying degree.

Adding a new block brings up the overlay and it doesn't scroll smooth but it isn't too bad, minimal lag.

Is that normal?

Edit, I tried it on another computer and it was a lot smoother scrolling. Still not sure what my computer needs to help speed this up. My computer is a AMD II X3 435, 2.89Mhz 2gb ram. Win Xp Pro SP3

Well it could be either your computer, server, or internet connection.

I've never seen this problem myself but I'm running - a i7 mac book pro w/ 4gb, vps server, and a extremely fast internet connection....

I've since tried it on another computer with the same lag. So then I tried using IE8 and all of the lag went away.

Same result on both computers. FF lag IE no lag. I'll reply if i learn more.
