I finally found the following posted by Noisette at

It works:
Read to the end – this is not just telling you how to set a home page
Open your iGoogle page.
Select the Tools menu - Internet options - General tab, and click "use current" to set up your home page.
Then in the same tab, at the bottom of the window, under "Tabs", and next to "Change how webpages are displayed in tabs", click "Settings". In the middle of the next window there is a drop down menu entitled "When a new tab is opened, open". Click the arrow next to that and select "Your first home page". Click OK twice.
That should do it!
