问题
I have a jQueryMobile website that is freezing up on IE10 (all other browsers appear to be okay). The behavior is strikingly similar to whats recorded here (https://github.com/jquery/jquery-mobile/issues/5695). I've taken a profile trace of the app at the time it happens, and it looks a bit like this (ordered by Inclusive time).
Here's a link to the full csv export of the profile (http://db.tt/JFTFyeGP)

I'm at a complete loss as to where to go next. From the look of things, something happens which causes 'blur' to go insane.
Here's the user viewpoint. User logs in, and navigates to the reporting section, where the choose a report to execute. A modal popup dialog appears, prompting the user for a start date, an end date, and possibly one or two other parameters. The user then clicks 'save'. A new window (tab) opens, presenting the report. The user keeps the report open, then goes back to the report list again. Selecting a new report, a similar modal parameter dialog appears, but this time, IE10 freezes solid, and you have to reboot, or force quit or similar to get control of the system back.
Any thoughts, suggestions, or other guidance will be greatly appreciated!
