Is my page size causing 100% cpu usage

 Even though most folks are at least at 1024x768, I still stick with the 800x600 (well, actually, a smidge smaller than that) size, because, not only is it the "safest," but it's also the size of all of the prefab Lectora templates. Whatever size you pick, I believe that it should never require the user to scroll either horizontally or vertically (horizontal scrolling is a particular abomination, in my mind!) and should allow for a fair amount of variation as to number and style of toolbars, taskbars, etc., that a user may have on their browser/desktop.

Just my $.02...
