I have looked and looked for a reason or fix, but can't find out why this is happening. Anybody know?

If I copy and paste an object, it lands as wireframe, losing all the fill and line info... and cannot be edited afterwards.

If I create an object and group the elements, it becomes wireframe and can't be edited.

If I have a grouped object and ungroup it, it becomes wireframe, blah blah blah.

What the heck is causing this?

I would really appreciate any help, after years of using CD, I have never seen this before and it's driving me crazy!

Thanks everyone, dee
