Diane, I don't know if this has anything to do with your problem but Apple recently applied a "fix" to Safari to block it from using outdated Flash for security reasons. If BPN isn't using flash here then this has nothing to do with your problem. If it does them update your Adobe Flash and Safari should work as it used to.
On the road for the rest of the month, heading for birds in FL. It's fine on my laptop (Snow Leopard) and here on the iPhone. Just hoping some update will fix it when I get home. I think an update of some sort started it but not sure which. Have been using Firefox at home on the Mac Pro (Lion) instead of Safari and its fine.
