We have a winforms application we recently upgraded to version-free Infragistics 2017.2.2039 and we are now seeing an intermittent bug where the context menu in one of our modules does not properly display and then freezes a shadow box on the screen causing the controls below it to not interact with the mouse and it does not go away until a restart of the application. We have tried throwing an exception to see if an exception being caught in the loading of the context menu could cause this behavior but have been unable to reproduce in debug. I have included a screenshot of the bug and the expected menu popup. We use the UltraToolbarsManager.ShowPopup method to show this context menu.
Hello Glen,
Thank you for contacting Infragistics. Please provide a sample that isolates and reproduces the behavior. Let me know if you have any questions regarding this matter.
Hi Michael,
This issue is intermittent and we have been unable to reproduce but multiple users have reported it after the upgrade, we were hoping you might have any ideas for troubleshooting. When throwing an exception the application properly displayed the unhandled exception, but it seems sometimes the context menu doesn't load fully and gets stuck.
