I have added a few banner ad images to my site. Some are on the forum page and other on web pages, but the names of the banners never appear in the web stats anywhere. I have clicked on one banner at least 40 times to see if Groupee web stats were recording the clicks, butu no mention of the banners anywhere. I checked the names of the banners in properties, so no confusion or mix-up there.

Perhaps I am miss reading something here but if the banners are pointing to a URL off of your site, than I dont beleive that the Apache module on your site will be tracking clicks on that banner. Apache is only aware of requests to it, not away.
