Itunes Browse Mode (streaming) Problem. When clicking an artist page, album page or song, itunes displays a blank white page.

This problem occured after I rebooted the OS (for other reasons) and started itunes again. In Browse (streaming) mode, I can search for an artist and it will display the search results. But if I click on any of the search results-- artist, album, or song, it displays a blank white page, instead of the artist, album or song page.

I have not made any changes to the OS or other software. Itunes has worked fine with no problems with the current version of OS and itunes, until I rebooted and re-started itunes.

If anyone else has experienced this problem and knows how to fix it, I would appreciate it. I called Apple support, but the support person was unable to provide a solution.
