Ok, so as an interim workaround, I have caught the UnsatisfiedLinkError which is thrown by the Form Designer when loading the VTK panel, and simply dont inialise any of the VTK specific components if this exception is thrown. This allows me to continue to work with the base (parent) form in the designer despite the VTK libraries not being loaded.
So I can design the form but still test everything using the IDE "run"button ...
