httpman,
1. Look at the Live Stats for this client's website and determine what (miniscule) percentage of vistors are using IE on a Mac.
2. Of course you already know the answer is one., your client.
3. Don't spend any energy making the website work with IE on a Mac. Find the page on Microsoft's website where they announce that IE on Mac is dead. Even MS says to switch to Safari:
http://www.microsoft.com/mac/product...ternetexplorer
4. Spend your energy on getting your client to switch to Safari or Firefox. Turn her on to tabs.
