My results\r\nFirst time the window is open (counter=0), it takes a bit longer, but then it runs smoothly. This test was performed on the iPad simulator with iOS 6 on a MacBook Pro.

Note\r\nThe bug comes from a customer, which has a document viewer app that uses a few ButtonBars; opening documents becomes slower and slower, but if the ButtonBars are removed, everything runs normally.\r\n\r\nNote that in the sample the new window is open and closed automatically, to make test easier; the original app of course doesn't have this behavior, but the problem remains.",
