Druapl - Admin access works on my computer but not always on clients computer

I've inherited a Drupal website and all seems fine.

I can login to the admin user and administer everything I want to. No problems.

My customer, using the same URL, with the same admin user credentials can see some parts of the Drupal admin system, but others keep on asking him to re-enter the username and password.

This happens on the Drupal Admin Dashboard and Content pages.
Client just gets a popup dialog asking for the admin username and password.
We renter the correct details and the dialog just keeps on popping up.

Can anyone help us to determine what is different on my clients computer / browser from that of ours?

We've tried in Firefox / Internet Explorer and Chrome.

Is this IP address related ?
Only difference we can see is that he is on Windows XP whilst we are on Windows 7 - surely that cannot make a difference?

So you and your client are logging in with the SAME user name and password, correct?
Did you try clearing the cache, or did your client try clearing the browsing history?
Also, are you both using IE. or Firefox, or something else?
And did you check Configuration -> People -> IP address blocking and see if any IP addresses are being blocked?

Drupal 7.16
That is very out of date, maybe you should back up the database and files and then update it to 7.24. Maybe that would solve the problems. Version 7.16 is 8 versions old.

Updated Drupal to the latest version and reset all passwords, flushed the browser cache and we're up and running.
