On Fedora 9 Preview, both i386 and x86_64, I've noticed that in package selection window (where I go to add emacs and thunderbird, etc...) I can no longer hold down the arrow keys to move through the list. Instead I have to hit the key repeatedly. I only installed F9 Alpha and Beta a few times, but I don't recall this. But the key repeat definitely works in RHEL4, RHEL5, and I'm 99% sure in F8 as well. Low impact, but a regression.
This doesn't only happen in package selection its an issue in the whole gui setup.
This should be better in rawhide.
