Thanks for the reply. I may not have been clear.
I have had 6.0 running for a few months now with no browser issues.

In the 6.1 upgrade comments I keep seeing posts that say the way to fix some things is to use Firefox. So I should have poised the question a little different.

It should be:
where are the places in the patched 6.1 release that do not work with IE ?

Since about 90% of the worldwide browser use is IE this is important.
