I have been using AdMuncher for quite a while and found it very good (despite my early whinging).
One thing on my system has been REALLY annoying me for months. My Linksys router admin is accessed via http://192.186
.1.1 and for a long time pages have been problematic in the management front end. They either don't display at all (common), only partially display or are malformed. Strangely my Desktop is the only device on the network with these problems - other computers work fine.
I finally traced the problem to AdMuncher (by pure chance) and adding 192.168.1.1 to the 'Don't filter of URL' personal filter list cures the problem instantly.
Given that I am about to change my wireless network (still waiting for delivery of the goodies) I have discovered this a bit late in the game but for anyone else having trouble with a router it may be worth adding it to trusted site lists in any suitable applications (obviously don't allow all access via a destop firewall or you may as well simply ininstall the firewall!)
