If you have not yet turned off Name AutoCorrect, you might try that.
Go to:
Tools | Options | General | Name AutoCorrect
In Access 2007, it's:
Office Button | Access Options | Current Database | Name AutoCorrect

That feature is turned off. Just to be clear, I actually deleted the field
from Tbl1 and added the same field name to Tbl2. I cannot make any changes to
Tbl1 and save without getting the error re field name not found? Any other
suggestions?

I found the problem. For the field in Tbl1 I had put a validation rule, I
thought by deleting the field it would have deleted the rule but it did not.
I clicked on properties of the deleted field in Tbl1 and found the VR.
Problem Solved. Thanks for the help.
