Mount_webdav has been updated

Question

Suddenly, my Mac started to annoy me with the folowing dialogue:
"mount_webdav has been updated. Do you want to allow the new
version to access the same keychain items (such as passwords) as the previous version?
This change is permanent and affects all keychain items used by mount_webdav."
The dialogue gives me two choices: "Don't Change or "Change All."
I choose "Don't Change," but the dialogue returns to my screen over and over while clicking "Don't Change" does not help.
Following this display, another dialogue shows up, displaying:
"WebDAV File System Authentication
Enter your user name and password to access the server at the URL "http://idisk.mac.com/(my_name)/" in the realm "idisk.mac.com."
Your name and password will be sent securely."
This dialogue is followed by the name and passwords fields and the "Cancel" or "OK" buttons. I then choose the cancel button. A few minutes later, both dialogues return to my screen with the same annoying questions.
I wonder about this procedure, because not only clicking the "DONT CHANGE" button does not stop the annoying dialogue from showing up, but also I was not informed or questioned, before hand, about this UPDATE; nor was I asked beforehand for my administrator password to approve such change in my system.
I also have my software updates' preferences checked off and selected to do updates manually only.
This dialogue does not make any sense if it will not accept my "Dont Change" choice!
How do I stop this dialogue from showing up? I appreciate anyone's help.

Thank you very much for your attention and support. The problem has been solved. I could not have guessed that in a million years!
I can not believe this solution, so simple, to the alien-like dialogue language which Apple makes a regular mac user like me have to face. I just can not understand why Apple does not forsee the solution for this complex dialogue (i.e. "mount_webdav"... duh... what is that? ...it sounds like I have to go to college for Computer Science to understand Apple's user interfacing language, nowadays...) so that average users do not have to sit here waiting for a good soul, like yourself, to reply. Meanwhile it has been days since I had to switch back to my old Windows PC becasue all my Macs were unusable!!! Thank you very very very much, once again!
