Nice!
Bugs: right click event does not work in Opera (10, but I am fairly `confident' this issue will exist in 9.4 as well). That may be Opera doing JavaScript differently, but still. Glitch: the tool tip is not very well readable on the leathery background (black text on dark background).
Firefox 3.0.9 fares a lot worse: the page is not centered meaning that the left-hand ornaments are obscured, and you get a vast stretch of background texture on the right. Image does not float properly either, it is displayed as a block element. Oh and the tool tips are dislocated: the offsets caculated end up a significant negative value (which makes some small tool tips end up like 50px above the cursor).
On Konqueror 4.2.2 you will not get any JavaScript at all and therefore no unit list at all.
I would suggest using a keystroke (much more easily implemented across different browsers) or custom image-button instead. Plus it is not a very nice behaviour to steal the context menu. For instance, if I want to investigate whether or not certain CSS tricks would fix the layout in Firefox 3.0.9 I must first disable the JavaScript, make my edits, and then somehow `fully' re-enable the JavaScript without having the reload the page... Copying/Pasting text will of course not be impossible, but not everyone uses the Ctrl + C, Ctrl + V keystrokes either.
And yes, I suppose many of these bugs exist in the old version as well.![]()
