That screenshot shows a 'Forbid http://10.28.1.2' option - which means that NoScript is currently allowing scripts. If you click on the menu item, then they will be forbidden. Perhaps the wording was confusing?

Religion is not the opium of the masses. Daily life is the opium of the masses.
True religion, which dares to acknowledge death and challenge the way we live, is an attempt to wake up.

Can't reproduce with NS 2.6.8.13rc3 and my own local server on port 8400 that was mentioned on the other thread (don't think I can try 90, sorry). There was no problem with Allow or Temp-allow any of: my-local-server, http://my-local-server, and http://my-local-server:8400 (allow only, from whitelist panel).
How are you accessing your local server? Anything related in the Browser Console when scripts are incorrectly blocked? (Ctrl-Shift-J)
*Always* check the changelogs BEFORE updating that important software!
