I used to be able to scroll in grid view, and as I slid the scroll bar, the thumbs would immediately move up or down. Now when I scroll, nothing happens until I make the scroll bar move, and stop. This is making it more difficult to browse through images I'm looking for.

Hi jimtron ,
What type of mouse are you using(Wired/Wireless) ?
Are the Mouse Drivers up to date?
Thanks for the response; I'm using a wireless mouse, though the performance is the same with my trackpad. I don't think there's a mouse driver for mouse, I didn't install one.
I just optimized and relaunched LR, and it's much better...still a bit sluggish, but I have a very large catalog (661k images).
Try optimizing your catalog in Lightroom fro File>>Optimize catalog.
Let us know if that helps.
