Details

STR:

1. Open Debugger on http://jqueryui.com/datepicker/
3. Select jquery-1.10.2.js
4. Create breakpoint at line 4762
5. Click inside the date field on the page
6. Breakpoint hits and the UI freezes -> BUG

If you select another browser window to make sure blur() happens and go back it works. Firebug solves this by executio

But, perhaps there is better way?

yuck. That is nasty.

Guessing there's an event our nested eventloop isn't dealing with properly.

cc'ing some folks.
