Lookie at what I found ... on the ORBX forum, notice ... this one is for V4, look at mine, it is for V3. Yet when I check with FTX Central, it says it is "updated". Aha ... the plot thickens!
Uninstalled Vector, am reinstalling, making sure to press the V4 option to download it from FTX Central ...
Update: Well, I uninstalled the old vector, and made sure I installed the "new" one. And in the configuration for elevation, it STILL SAYS P3D V3. Off to the the Vector Support forum.
