When I select all of the wireless connections in the mapping tab, I get the proper mapping colors when doing a manual mapping.
However, when attempting to focus on a single SSID router, no matter where I am on the map, it logs all cells with purple. I happen to know that this is inaccurate as I then minimize Wirelessmon and can see the target in the upper right hand corner and the single strength through Wirelessmon registers a different strength.

Any ideas?
