Hello
Just installed version 19 over top of version 18 like I always do, trying to create a quick config and I have this error box with the following message:
Object reference not set to an instance of an object.
at eval_n7.eval_a(Object A_0, FormClosingEventArgs A_1)
at System.Windows.Forms.Form.OnFormClosing(FormClosingEventArgs e)
at System.Windows.Forms.Form.CheckCloseDialog(Boolean closingOnly)I then close it and have another error box with this following message:
Collection was modified; enumeration operation may not execute.
at System.Collections.ArrayList.ArrayListEnumeratorSimple.MoveNext()
at System.Windows.Forms.Application.ExitInternal()
at System.Windows.Forms.Application.Exit(CancelEventArgs e)

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)Not a clue what it all means, should I have removed version 18 before installing v19? I have rolled back to v18 which works fine

Thanks for any help
