Menu Navigation Issues w/ .24

After upgrading, there seems to be a problem in navigating with the up/down buttons.  If I’m navigating a large directory tree (wirelessly, from a network share on my PC), hitting up or down will often skip ahead 2-3 spots… sometimes 5 or 6.  Sometimes hitting the button really quickly seems to help, sometimes not.  I often have to alternate hitting up, waiting to see where the cursor stops, hitting down, waiting to see where it stops, etc. until I can narrow in on the selection I want.

I upgraded to .24 and added wireless at the same time, so either could be causing the issue.

Any ideas?
