First of all, thank you for this amazing tool. I have been using it for quite a long time. However I found a problem with JKI Flat UI Controls that only appears if you launch LabVIEW from Visual Studio in a debug session. To replicate the issue, you can just simple create an empty project in Visual Studio (tested with VS 2015, VS 2017 and VS 2019) and set LabVIEW as the Local Windows Debugger. If you launch a debug session, you don't have to open any project, and still LabVIEW will crash after approx. 30 seconds and throw an exception. The problem has gone after I removed JKI Design Palette and JKI Flat UI Controls 2.0 from LabVIEW.
