I just went to "Edit Account", and added some text to my signature (to fix the truncation now the bug has been fixed). I also selected "store my login in a cookie for a year". After clicking "submit", I got a page saying "You do not have access to this page" or similar, and it kept redirecting itself to that page in an endless loop. I manually went back to the main page, and clicked "View Account", and got the same problem again. I had to logout and back in to fix it.
This is with Mozilla Firefox 0.8 on Windows 2000. I made almost identical modifications to my account last night in IBrowse 2.3 on OS4, and had no such problem.
Edit: And looking at my sig, it seems that truncation problem is NOT fixed :-(
