I think I've decided to go back to the big, bad Bear, too.  I also notice that it seems to work better in 4.61 than it did in 4.51.  IERenderer seems to work better yet, but a daily e-mail message I receive throws an error message every time when I use IE, and displays just fine if I use Bear.  I wouldn't mind that TOO much, if it weren't for the difficult, and probably unavoidable, process for changing back and forth, requiring that everything I'm working on be shut down first.

In case it's useful, the error that I get from this particular daily e-mail message is:

	The website declined to show this webpage
	HTTP 403
