Issues Deleting Objects

I have been editing my skybox (merging two together) and have run into something odd.

When I am editing various objects, I can simply click "Edit linked parts", highlight an object and unlink it. It turns yellow, and typically I can move it or delete it etc.

Sometimes the delete doesn't work. Even if its unlinked and I can move it all over the place on its own, I still can't delete it. It almost seems like to delete it I have to delete a certain number of objects (or a key object) around it. Isn't this what unlinking is supposed to get away from?

Its quite frustrating. I have these pieces of my loft just floating in the air and I can't delete them. Is there a catch to some of these objects that I might be missing? Is there a "no, really... totally unlink" button?


I hope I'm asking this in the right place - if not, forgive me.

Check you don't still have "edit linked parts" ticked in the edit options... even if there is only one prim, this will stop you being able to delete it (the number of times I've had this problem!).

Cool, I'll give that a shot.

Also, where is the "undo" button for deleting PRIMS? I get the item and can bring it back, but I see no un-do option, or its blackened out in the menu.

there is no undo for delete, only to rerez the object from the trash folder and reposition
