Description of problem:
Network indicator *menu* very often vanish when I click at "More..." networks and it happens in both cases - when I scroll the list using mouse wheel or scroll dragging the right slider. One needs to click on network-indicator again, go to "more networks" and sometimes it is a real race will one be fast enough to click on preferred wifi network to connect to or experience menu vanishing again.

Version-Release number of selected component (if applicable):
gnome-shell-3.0.0.2-2.fc15.x86_64
NetworkManager-0.8.998-3.git20110419.fc15.x86_64

How reproducible:
Very often

Steps to Reproduce:
Can't reproduce. My wifi neighbourhood is "interesting", nm-tool gives about
60 different wifi networks and I believe those all are in network-indicator list, so maybe this is happening when some wifi networks disappear (low signal strength or power off wifi router) and some appear.

  
Actual results:
The menu shouldn't disappear until user change focus.

Expected results:
Menu shouldn't disappear as it is hard to connect to preferred network if that is happening

Additional info:
abrt doesn't complain so I believe it is not crashing.
