Asa pleasantly surprised me by pointing out the following:
mpt omits something that has to be one of the most important usability flaws in IE, that the main browser scrollbar has a fat border to the right of it forcing the user to actually look where he puts his mouse pointer rather than just tossing it against the edge of the screen and knowing you’ve hit your target.
Since I rarely use Mozilla or IE maximized, I wouldn’t have noticed this. Mozilla happily eliminates the typical window border and takes advantage of Fitts’s Law. In brief testing, it seems almost every Windows application suffers from the border on the edge of the screen. Oddly, Lotus Notes was one of the few that also got this right. With the inconsistencies between Windows apps, I’m not surprised that mpt missed this one. I agree that it is a major flaw in IE.
<rant mode="pet peeve">Speaking of Fitts’s Law, it’d be nice if Back were returned to the image context menu of Mozilla. The context menu is by far the fastest way to go back and I’d say used far more than scrolling. This is especially annoying when you have images blocked or a large image with transparent edges that takes up most of the page.</rant>
