In the "Launch new instance(s)" dialogue, after adding one of the top, visible security groups listed, all security groups below those which are visible show up as "undefined".
Version: rev 105 on Firefox 3.0.11
Procedure to reproduce:
1) Add more security groups than can be shown within the security group picker in the launch dialog. For Ubuntu and Windows this seems to be 4, so 5 or more security groups are required to produce the bug.
2) Select an AMI to launch.
3) In the launch dialog, select and add one of the immediately visible security groups.
4) Scroll the available security groups list to see that the last items in the list now appear as "undefined".
Workaround:
Add the security groups needed which are initially hidden before those at the top of the list.
A fix for this issue is forthcoming. Please test the attached build and let me know if the problem has been fixed.
The pre-v107 build
Fixed in v107.

Still having problems with the undefined items beyond those visible.
