Thanks Chris,

Cache Record Lookups was checked as it has been for some time.

On my old 550 I had this checked also.
If I unchecked it things broke.
When I got the bx box figured it should be the same?

I have read where this is bad but every time I would un-check it my
world blew up so I checked it to make the issues go away

It's is now Unchecked and everything hasn't blown up like before.

Thanks again
