Rory B. reported:

System.NullReferenceException: Object reference not set to an instance of an object. at SystemTrayMenu.Business.Menus.<.ctor>g__LoadSubMenuCompleted|21_15(Object senderCompleted, RunWorkerCompletedEventArgs e) at System.ComponentModel.BackgroundWorker.OnRunWorkerCompleted(RunWorkerCompletedEventArgs e) at System.ComponentModel.BackgroundWorker.AsyncOperationCompleted(Object arg)

It said file not found.
I tried to repeat it and it did not happen.
I had clicked on the icon in the taskbar instead of the system tray.
I did the hover over method to get to the folder I wanted to open and when I clicked on the folder, I got the error.
It happened a few times yesterday and then no more.
