Two same-named templates

[Tim Murray]

System: MacBook Pro, 10.6.2, PowerPoint 12.2.3

I have one custom PPT template in my user templates folder, named TBT.potx.
It is the only file of that name on my entire hard disk. When I open my
regular presentation and click Slide Layouts, I get three entries:
- All Layouts
- TBT
- 1_TBT

To remove one of the TBTs I thought of an approach to clean house by force,
so I changed its file name to temp.potx.

When I reopen the slides, the two errant templates are gone. So far so good.
But now it gets stranger: If I name the template back to TBT, both TBT and
1_TBT come back!

Sounds like a bug to me. Any ideas?

I will repost with different behaviors. It's getting weirder.
