For me the script error ended a couple of weeks ago, not sure of date. I was able to come back on 3FC (knock on wood) and post as usual, plus enjoy reading the forum. I don't post here every day but the site means a lot to me.
I didn't do anything. I have IE and like it and never even entertained changing to FF, which is just not a browser I would use for my purposes. I also do not use two browsers on one computer as for me it causes problems.
I only experienced the script error on this site and assume the owners fixed it and I thank them! But for me it had nothing to do with IE.
Huzzah, nice to have it working again!
