Ok all,
The good news is I was able to make this site crash on my computer using IE6. I have made some changes and this does not seem to happen any more. The bad news is that the changes involve removing some important IE layout hacks, so some posts are going to look funny for a while, specifically posts where there is a large-ish avatar linked from another site. You'll know what I mean when you see it
Again, this is an IE only bug. Please let me know if you continue experiencing crashes as it is possible that there is another issue here. In the meantime I'll be working to find a permanent solution to this, bear with me.
