Different effects of sign-on on different computers

Different effects of sign-on on different computers

I ended up with 2 computers.  On one computer, when I upload a ZOHO database that I DO NOT want viewers to make changes, I get the normal top heading, with SEARCH, and on the top Right SIGN IN .  Without signing in properly no one can make changes.  JUST WHAT I WANT.

On the other computer when I do exactly the same and upload, I only get SEARCH on the left and SIGN IN is not there , and even I cannot make changes.

Can you tell me what is going on.  And how I can make all of my several CREATOR databases to stop changes unless I sign in.
