With the possibly exception of older posts carrying images too wide to fit the current content width, the site should now again be capable of running at 800×600 if anyone should be so inclined.
Another thing, if anyone stumbles onto a bug with the menu bar messing up the site please let me know. I’ve had a report of it and seen it once myself.
PS: This is entry #444 :)

Excellent! While I run my system at a pretty obscene resolution, my browser windows are typically less then 800px wide, so I no longer lose the side bar.
(And it looks great too)
