We shouldn't be surprised.
After reading all the negative feedback on MS news groups about IE6, I still don't know why they released it!
I'm still using it, but this thing seems to be full of holes and problems.
still using 5.01 here with SP2 installed. I have no reason to update it and seeing all the problems that are coming out with 5.5 and 6, I'm glad I didn't.
Besides, I use Opera as my main browser anyways...IE is just a backup
