    Hi,

    In Chrome the dropdownlist becomes unusable once you move to another browser tab then come back.  When you click on the dropdownlist it will expand then close straight away, preventing you from being able to change the selection. You may need to switch tabs once or twice for this to occur.

    Chrome version: 20.0.1132.17

    Steps to reproduce:

    1. With Chrome, goto http://demos.kendoui.com/web/mvvm/widgets.html 
    2. Open a new browser tab.
    3. Switch to new browser tab.
    4. Go back to first tab.
    5. Click on dropdownlist.
    6. Repeat steps 3, 4, 5 once more if the dropdownlist still works.

    Can someone verify this please?

    Hello James,

     
    As I answered in the support thread opened on the same subject, it seams that the focusout event is triggered when the user leaves the tab, but focusin is not raised when open the tab again. Thus the toggle logic messes up and the DropDownList widget stops to work. We addressed the problem and the fix will be included in the next internal build of Kendo UI. For now check this jsBin demo, which shows the possible workaround. Please note that this issue occurs only in the Service Pack Q2 2012 release of Kendo UI.

    Hi Georgi,

    Thanks for the reply. The workaround does fix the issue most of the time but it still does happen.

    Are you able to advise when can we expect the next internal build? Is it days, weeks or months? So that I can look at using a previous version or another library if the fix is too far away.

    Hello again James,

     
    The next internal build is scheduled for the beginning of the next week. We release internal builds as soon as there are enough bug fixes. 

    All the best,
