Checklist

  • I have searched the issue tracker for open issues that relate to the same problem, before opening a new one.
  • This issue only relates to a single bug. I will open new issues for any other problems.

Describe the bug

Very intermittent. Not specific to any one app I am working on. This one happened just as I clicked on the "okButton" defined in ShowTestCaseDetails() in the sample code below

How to reproduce

I just clicked on the "okButton" to close the window
