Normals (EX9.Geometry Mesh) crashes renderer when going to fullscreen

When using Normals (EX9.Geometry Mesh) in beta21 and going to fullscreen the renderer crashes and stays gray even after going back to windowed mode. Renderer (TTY) says:
“cannot reset device try different parameters”.

Resetting the renderer (Alt + rightclick) doesn´t help either
the renderer becomes black again but the object is not rendered. Renderer (TTY) says: * [ error occured in TMex9Effectnode]( error occured in TMex9Effectnode): Zugriffsverletzung bei Adresse 00404AA4 in Modul ‘vvvv.exe’. Lesen von Adresse FFFFFFDC

Tested on 2 machines:

Windows XP Pro SP2 / NVidia 8800 GTS
Windows XP Pro 64 SP2 / NVidia 8800 GTX

Tried without and with SlimDX installed.

Works fine with beta20.
