Beta27 dialogues missing - can't load or save anything including patches

Hi, been having some problems with beta27. Suddenly all file dialogue boxes have disappeared, eg load and save (including meshes, textures and obviously patches) both from right-clicking in patches and from the middle mouse button file menu.

…meaning I can’t save anything I’ve done…

Has happened twice today after messing about with mesh loading a lot (both xfiles and xmaspack assimploader)

windows 7, x64
nvidia gtx470

cheers

Can’t quit either. (unless I say “don’t save+close” to everything)

mkay…sounds like vvvv is in a crashed state…are you having a tty open when this happens? what does it say?
