found a reproduceable way to create a strange behaviour of shaders Technique being NIL like @karistouf described in another thread.
it seems to be related to the first frame evaluation of Queue (EX9.Texture)
All Bug description is related to Beta23.
in Beta23 the bug results in an application error, when closing vvvv:
Exception EInvalidPointer in module vvvv.exe at 000047C9
in Beta24.1 also the “nonBuggy”-patches result in endless running complaints in TTY-Renderer.
