mouse cursor bug?

[Leon]

Hi all,

I finally figure out how to reproduce this bug though I have known it
for a while.

1. Fire up gnus
 
2. middle click a group with a small number of unread articles so that
you won't be interrupted to enter the number of articles. Make sure
you mouse cursor won't be on any clickable text when enter the group.

*NB*: You may need to hold down the middle button slightly longer than
usual when middle click the group.
                                  
Your mouse cursor will still has a 'hand shape' after entering the
group. I have recorded this process in a gif file located here:

Hope you can reproduce this and fix it.
