    Experiencing an odd issue with IE11 on windows 7 and windows 8.1 (as desktop program).  Not an issue when I tested on Chrome (win7, win8, mac) or firefox (win 8). 

    Starting with the Basic Usage script for the validator from the KendoUI demos.

    Add the <option></option> to the Start Time select options, this will allow the empty label to be the default when the drop down loads.

    **NOTE: I can only reproduce this when using 'FullScreen' in the dojo, using the dojo side window, it does not have the issue.

    Load the page and don't click anywhere else on the screen and click in the middle of the 'Start time' drop down to open the list.  When the list expands the validation error for the field being required is now shown.  The blur event for the validation appears to have been triggered.  This is only happening in this one environment, so I don't feel this is the desired result.

    I created an example at


    It has multiple drop-downs.  The problem that I am experiencing only happens the first time on any of the drop downs on the page.  Once the blur event occurs for the first drop down when opening the drop down, the second dropdown will not have the same problem.

     Any ideas would be appreciated.
