I have added a choice to a focusable java.awt.Window and I have added few items to it. I have made the window as well as it's parent visible. When I try to select the items from the choice a few times, First time I was able to select but subsequent times, the items are not selectable using mouse. When I click on the item, neither the item is getting selected nor the drop-down closes.

This is reproducible only from JDK7-b02 and not reproducible on b01. Hence it is a regression from JDK6. Not reproducible on unix platforms. Choice works fine when added to Frame/Dialog.

Run the attached test. Click on the choice added to the window. Try selecting an item. Repeat this a few times and you will see that the mouse click is no longer able to select the item from the choice.
