A bit off topic (apologies for hijacking the topic), but I've noticed that the jQuery version of the page actually has a greater download requirement than YUI (and only slightly less that Prototype).
jQuery: 177 KB YUI: 164 KB Prototype+Scriptaculous: 178 KB This could be reduced a little if the plugins used by it (dimensions and form plugin) were easily available in compressed format (rather than users downloading directly from SVN - which also has the downside that you don't get the revision number or date (Trac doesn't have a checkout feature does it?), so you don't know if you have the latest version). However, this ignores the fact that for this file size you should be able to do far more than the others in the demo without any additional downloads. Back on topic: I noticed that if you hold the mouse button down it scrolls through the months quite quickly. Also if you keep holding it then move off, the scrolling stops. Then release the mouse button and move back on and it resume the scrolling. Not sure if that would be classified as a bug though (probably not). So I guess this is due to how it is implemented as compared to the datePicker by Kelvin (Ext uses mousedown, mouseup; datePicker uses click). Maybe ClickRepeater should be ported over to jQuery?
