                                  • We are using a SplashScreenManager to control a WaitForm. This is to show progress on long running tasks because our application is not multi threaded.
                                    We sometimes notice, when running longer tasks, that the WaitForm "jumps" behind the main application window. Even tho, it is constructed with ShowOnTopMode set to "ShowFormOnTopMode.AboveParent". This is a problem, since it is no longer possible to the user to see that the application is actually working.
                                    We tried using the deprecated "TopMost" variable instead, but this forces the waitform above all other applications, which we do not want.
                                    The waitform is only changed by sending commands to it by calling SpashScreenManager.SendComment and handling the command in WaitForm.ProcessCommand

                                    It seems like this happens when the application goes into "Not responding" mode. Because of the message loop not responding.
                                    Do you know why this might happen?
                                    Sincerely

                                  Hello,

                                  Please share a project where this behavior occurs. You can copy your real application and remove all unnecessary forms from it. It will be sufficient if you create custom fake data to bind it to controls.
                                  If it is necessary to execute specific steps to reproduce the issue, please specify them.
                                  I look forward to your response.
