Comment 1 Richard D. Payne 2000-10-17 13:57:00 UTC

Still present in RC1.

Comment 2 Phil Copeland 2001-06-04 16:52:39 UTC

What machine, RH release if any and kernel?

Comment 3 Richard D. Payne 2001-06-04 16:57:15 UTC

I think this was originally filed against a 7.0beta version. I can retest with
7.1RC1 if you'd like.

Comment 4 Phil Copeland 2001-06-24 17:45:24 UTC

(going through cleaning up/tidying up old bugs)

Is this still true of the Gold ISO images?
I'm making an assumption here that you're using a Nautilus box with an AGP card
of some sort as thats the only alpha I'm aware of that has an AGP slot on it
