If you want to turn off those annoying messages:

Goto ToolsOptionsError Checking tab.

Under Rules, uncheck everything that you don't want to be bothered by. I
have then ALL unchecked.

When working on my spreadsheets I enter a simple formula into a cell, e.g.
=345+25, hit enter, and the Smart Tag appears showing the error that the
cell
is not protected. I then must click and tell it to ignore the error and
this
continues until I'm finished with all my entry.
I go to the next spreadsheet and enter an identical formula: =345+25, hit
enter and no error messages appear. Doesn't seem logical to me. (I hate
that when that happens.)
Thanks for any and all assistance.
