Why do some of my objects not appear in the editor?

I have added approx. a dozen objects on the layout now but some of them just don't appear in the editor, the first four or so objects appear ok , but after that I can't see them anymore.

all I can see is the bounding box when I select them, is that normal?

Maybe you set their opacity or their layer opacity to 0. You could try deleting everything except the invisible objects in your .cap and upload it somewhere, so we can take a look.

Here's a cap

everything after the object "tornade" doesn't appear...

(how can I attach caps to my posts BTW?)

Ah, it looks like a bug with the 3D box object. If you delete it, everything seems OK.

Ah yes you're right, the 3D box object is somehow hiding everything lol.
