Here's my situation and what I did (in as great detail as I can manage on 1 cup of java...)
I had a skybox I'd built, with a pool and pool tubes. I decided that I wanted to rebuild on land level, so went about taking items and deleting others.
Two of the pool tubes still counted against my prim allowance but I couldn't see them.
When I went to the 2 prim platform I left there (as a marker of sorts), if I brought up "About Land" and clicked "Show Owned by Parcel Owner" they appeared as invisible objects, highlighted in white. I was unable to select them and ctrl-alt-t as well as other things didn't help me to get them back.
THE FIX:
I went to where I knew the objects were
I brought up "About Land" and clicked "Show Owned by Parcel Owner", leaving that window open, but minimized to highlight the problematic objects
I right clicked the platform and brought up the Edit window (I imagine you could also bring up build, but this is what I did).
Once both those windows were up, I left clicked outside the range of the objects, held down the left mouse button and dragged, bringing up the selection box/outline.
As soon as the 2 objects were within that "box"", I released the mouse button and BLAM there they were in all their "originally created form" glory.
At that time I was able to right click/take or right click/delete.
YIPPEE
Hope this helps people who've been plagued by prim issues
