Looks like normal behaviour to me, but you probably mean what I meant here:
which basically means when the scrollbar appears it moves everything to the left and then the content is still centered in the now smaller space. I dare to claim the 1px border was added exactly for this. To make the scrollbar appear and have all pages look the same while having a minimal amount of scrolling possible on the mainpage. I don't know which is better.

also there seems to be a 1 or 2 pixel high line on the very top of the mainpage that makes the scrollbar appear even though it is not needed. Then again this keeps the main page aligned and indented like on all the other pages. Still strange though.
