Forum:Editing within IE made difficult

Some strange behavior I noticed while trying to edit Wikia using Internet Explorer version 7.0.5730 I was trying to edit the page for Venice when my laptop, a P4 running WinXP, would lock up. The cursor and IE would become non-responsive, and I needed to force an "End Task" shutdown of IE. The problem seemed to mostly show up during a Preview before I submit a change to Wikia.

Now I have an utility on my machine called SmartRAM (from IObit, incidentally). The CPU Usage indicator was at 100%! I waited several minutes for the processor to finish whatever it was doing but nothing changes.

I hope someone can shed some light on this, and if not then consider it fair warning for others thinking about editing. Maybe the best thing to do is write out a draft in a word processing program and save it, then cut and paste to Wikia?

PS. I did finally complete my editing work, using Netscape Navigator 8.1 as a workaround.
