Hi, I have found a very small bug in the Monitor. If you create a limit group and set it to whitelist and assign a few computer to the whitelist, when you come back to edit the limit group, the whitelist box will have the text blacklist over it instead of whitelist.

Thanks Sylvain, should be a trivial fix.
