My right column is empty in my iGoogle home page but only on my iMac the gadgets have moved below the left 2 columns and connot be moved back to the right column.  My Win 7 PC with IE8 and my iPad with Safari display properly.

I am using an iMac with OSX 10.4 Tiger and Safari browser.  Changing the browser to Chrome is not possible with Tiger because Chrome will not work with that OS.  I also have Firefox on my iMac and the Google page displays properly there but i want to use Safari.  The only thing I have done that could possibly create this problem is to install a new HP 4500 all in one officejet printer but I don't see how that could make a difference. I have tried to add more gadgets but they also will not go into the right column.

 I tried to change the display to 2 columns to see if that would then allow me to change back to 3 columns but when I change to 2 columns the right column is empty and everything is in the left column and nothing can be moved to the right column.  So I am still without a right column on my iMac 10.4 with Safari.  I checked for updates but I am up to date with my Apple products.
