Me too, I have IE5.5, and I do not have the same problems you have. I only can't see the code from a frames page.
I mostly browse with Opera as it is faster, and it does not keep extremely well hidden track of all your movements on the Web (these secret files get fatter and fatter). It also gives me the opportunity to see the code of frames pages. The only disadvantage it has, is that it is VERY strict about the w3 norms, and lots of sites don't display as one is used to view them in IE5.5.

So you may want to re-install 5.5. Perhaps, before you do so, clean up the temp and temp int files, and ctrl+alt+del close all running progs except systray and explorer.
Success!

If you don't work against time, time often works for you.
