Unhandled exception when adding sceneries to a Group

[Lucky67]

I can create empty groups but can't populate any of them.

As soon as I hit the Submit button I get an unhandled exception, here the relevant excerpt

************** Testo dell'eccezione **************
System.NullReferenceException: Riferimento a un oggetto non impostato su un'istanza di oggetto.
   in P3DV4AddonOrganizer.MainDialog.PopulateGroupTree()
   in System.Windows.Forms.Form.OnFormClosed(FormClosedEventArgs e)
   in System.Windows.Forms.Form.WmClose(Message& m)
   in System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

This is a pretty fresh installation with a very few add-on sceneries added so far.

V 1.34 b06

Did I miss something? Any prerequisite?

Thanks in advance to the creator of this amazing tool.

Ouch. Sorry about that. That bug must have crept in with the latest version (=today...)

Fixed in version 1.34 b07, which is available for download now.

Best regards

OMG, your support is terrific!

Indeed this annoying bug was wiped out with the latest build.

Thank you very much again Oliver!
