I had the exact same problem. The quick and easy way is to turn PROXYNOTICE to 0...if you think about it, why do you care if you have a few proxy dudes hanging around? But, the only way I know of to get rid of them if you really want to clean house is to download Superpurge at http://manusoft.com/Index.stm. Select a hard purge, and go hunting for them. That is the tough part, finding which entities are actually causing it. Some of them are apparent (it will list the app as civil) and some not so. You can also email Owen (maker of the software) and he will give you good hints as to which ones they are...and if youre really stuck, he will take a look at your file. Make sure you back up the templates first!!! Superpurge will allow you to do some ungodly things that will bring on the blue screen of death....
Happy hunting,
Tom K.
