Thanks for contributing! Can you provide a unit test for this fix? Also can you please sign our CLA: http://jquery.github.com/cla.html

It looks like the check being removed is a fix for an IE bug. See #7623 and bb79b41.

@tjvantoll, another fix with no tests :/. Perhaps, someone could write a test for 7623, and then a test for this?

@mikesherov , actually i was not even able to run the tests. Can you please point me to some docs how to setup and run the tests? I already signed the CLA.

@tjvantoll , true I didnt test on IE. The bug description mentions this is a problem on all browsers.
On FF, the problem of #7623 happens if you set the focus before hiding the datepicker. Note how I inverted the order... unfortunately I have no access to IE to test it myself.

@schettino72 To run the tests you can open the main datepicker test file in a browser.

I tried this out and it indeed fixes #7765 but it also reintroduces #7623 in IE 7 - 10.

@tjvantoll sorry I have no access to widnows/IE maybe after a few days I can get a machine to test it...

Thanks again for contributing, @schettino72! We're going to close this pull request for the time being until it can be properly tested in IE and we can be assured it doesn't cause a regression for http://bugs.jqueryui.com/ticket/7623 as @tjvantoll mentions. Please let us know when you have time to make progress on this.

Thanks again!

Any update on this one regarding the working version on IE 7-10 ?
