Disappearing lighting position and lanterns

[jomer]

Using a mac running 12.5.1 then updated to 12.5.2. I have updated to stop problem but it has not helped. When I draw a lighting position (metric 15m) using lighting position insert. Had some problems with it disappearing but eventually it stayed on the drawing. When I try and drop a light on to the bar using lantern insert tool when I click off both the light and lighting position vanish. This also happens when I put the light anywhere. Just tried using light position and a selecon lamp sort of worked but once clicked away it is no longer selectable.

Any ideas?

Is the "None" class visable or are you drawing in active only calss?

During object preview classes are ignored, but once the object is placed in the document class visability takes over amd may make the object vanish.

Thanks Kevin. Was in active class only and had turned "none " off for renders. As always quick and efficient answers. Cheers.
