Hello, everyone

it looks like i've got a very strange problem. It appears in IE6.0 and is visible only on pages of substantial length. This is why i do not post the code here, but instead have put the example file here.

The paragraphs are supposed to have a margin of 6pt from the right, which works fine for the very first one, but then that padding "leaks" somewhere, so that each following paragraph has more and more narrow margin, until eventually it becomes negative and the text just sticks out of the border!

My aesthetical feelings are crying
Does anybody knows what's the problem, and how to fix it?
Btw, HTML4.0 validator finds no problems with that page, so i don't think it's invalid markup.
