When running through the walkthrough-1 I played around with re-projecting during the section on using the info tool to show park information from the DM Solutions WMS. Whenever I was using a plain WGS 84 projection, the info tool produced information for the parks I clicked on, but with any NAD83 projection I tried, no information was found. I tried NAD83 / Alaska Albers, NAD83 / Georgia West (ftUS) and a few others. Changing back to, for example, WGS 84 (deg) and the info tool works again.
By not working, I mean it behaves as if I clicked no-where near a point of interest. I suspect the coordinate transforms for the info tool are not working correctly, and only work for the default CRS because, well, it's a default.
