Remote Interpreter "test connection" yields a hidden modal dialog

Hi All.  Anyone seen behavior where the resulting dialog following a click of the "Test connection" button on the Remote Python Interpreter dialog, yields a hidden modal dialog box?

I can Command+Tab and the dialog sometimes appears for a split milli-second then disappears.  Have tried to "wake it up" by trying to quit the app via Activity Monitor, but to no avail.  It seems the only way to get by this is to force-quit the app.  I imagine this should be harmless, but am welcome to any ideas.
