RSS feeds in IE7 on Vista - Fat Frog

Hello,

I subscribed to some RSS feeds in IE7 running on Windows Vista Enterprise.
What's been bothering me is that the titles of the feeds do not change from
bold font to regular font after the feeds have been viewed and the browser
has been navigated to different websites, until I close the IE7 browser
window completely.

In the "Feed Settings", I have already selected "Automatically mark feed as
read when reading a feed". It doesn't happen on another Vista (Ultimate)
computer that I use.

Thanks and regards,
TL
