+defined explicitly as "images" (e.g. ad banners). Depending on the URL itself,
+it is sometimes hard for Privoxy to really know whether there is indeed an ad
+image there or not. And there are limitations as to what Privoxy can do to
+"fool" the browser.
+
+For instance, if the ad is in a frame, then it is embedded in the separate HTML
+page used for the frame. In this case, you cannot just substitute an aribitray
+image (like we would for a "blank" image), for an HTML page. The browser is
+expecting an HTML page, and that is what it must have for frames. So this
+situation can be a little trickier to deal with, and Privoxy will use the
+"Blocked" page.
+
+If you want these to be treated as if they were images, so that they can be
+made invisible, you can try moving the offending URL from the "+block" section
+to the "+imageblock" section of your actions file. Just be forewarned, if any
+URL is made "invisible", you may not have any inkling that something has been
+removed from that page, or why. If this approach does not work, then you are
+probably dealing with a frame (or "ilayer"), and the only thing that can go
+there is an HTML page of some sort.
+
+To deal with this situation, you could modify the "block" HTML template that is
+used by Privoxy to display this, and make it something more to your liking.
+Currently, there is no configuration option for this. You will have to modify,
+or create your own page, and use this to replace templates/blocked, which is
+what Privoxy uses to display the "Blocked" page.
+
+Another way to deal with this is find why and where Privoxy is blocking the
+frame, and diable this. Then let the "+image-blocker" action handle the ad that
+is embedded in the frame's HTML page.

+
+3.12. I cannot see all of the "Blocked" page banner. All I see is a bright red
+square.
+
+There is not enough space to fit the entire page. Try right clicking on the
+visible, red portion, and select "Show Frame", or equivalent. This will usually
+allow you to see the entire Privoxy "Blocked" page, and from there you can see
+just what is being blocked, and why.
+

+
+3.13. Can Privoxy run as a service on Win2K/NT?
+
+Yes, it can run as a system service using srvany.exe. The only catch is that
+this will effectively disable the Privoxy icon in the taskbar. You can have one
+or the other, but not both at this time :(
+
+There is a pending feature request for this functionality. See thread: http://
+sourceforge.net/tracker/?func=detail&atid=361118&aid=485617&group_id=11118, for
+details, and a sample configuration.
