Managed to figure out how to manually install the Radar Gauge into the Ariane 737, which will presumably allow it to be installed in anything else that the WXT Editor goes awry on

What was happening, was that the WXR Editor was failing to add the list comment for the new window with the radar gauge up at the top of the panel config file for some reason. It would add the new window with the panel data at the bottom of the config file just fine, but without that top line to tell FS that there was another window, it wouldn't show up, so you just have to manually add that line and number it in sequence.

Might want to consider adding a walk through on that to the manual.

Even though I've spent most of the day faffing around with things to get it to work, now that I've sorted out all the problems I was having I can actually use the thing at last. It looks like it will be good fun to play with.
