I just tracked a problem with an app appearing minimised in the task bar down to a call to setUsingNativeTitleBar() on my DialogWindow derived app. I’m guessing this doesn’t happen with the demo app, but I’m wondering if others have seen this behavior, or if it’s a known bug.
The window appears as expected when running under the debugger, but when running without the debugger, the window is minimised. Commenting out setUsingNativeTitleBar() fixes the problem.
