AntiSpyware Beta ignores allowed startup programs

Every time Sophos Anti-Virus updates on my computer
InterCheck Monitor cannot start until I click allow. I
have clicked allow several times but the setting is not
making any difference.

From the log file...

The user mtg, has decided to allow the startup file
C:\Documents and Settings\All Users\Start
Menu\Programs\Startup\InterCheck Monitor.LNK to be added
to the startup directory.
