This is unlikely to be a bug. If you post a screenshot of the create waypoint screen with all your waypoint info entered, we'll be able to tell what is wrong.

Thanks Bjorn

Tried this but still greyed out. I also tried adding it via setup and via the map directly. The same on both counts ..just cant save the user waypoint...seems like a bug?

When this happened to me, I had an incorrect coordinate format (in my particular case, I had common n/e instead of the required capital N/E.)

Sky demon will allow me to create a user waypoint but the green save button is 'greyed' out so I cannot save. Thought this was a bug so reinstalled sky demon but still the same. Any ideas?
