With the new version of toggleExtension, the vextensions defined in one's settings file can only be toggled on POS-level constituents. There is one case in which this is problematic--the conjunction of unlike verbal categories. Cf. this example from the English manual:

```
(NODE (VB (VB witen)
(CONJP (CONJ o+der)
(HV habben)))
(ID CMANCRIW,I.52.125))
```

And this example from Greek (with verbal dash tags: hence the problem):

```
(VPRA-IMPF (VPRA-IMPF σχολάζοντα-σχολάζω)
(CONJP (CONJ καὶ-καί)
(VPRPA-PRF-PASS σεσαρωμένον-σαρόω))
(CONJP (CONJ καὶ-καί)
(VPRPA-PRF-PASS κεκοσμημένον-κοσμέω))))
```

One solution might be to refine the idea of what counts as POS level (perhaps in combination with whatever is done to confine the set of legal POS tags) based not on the structural level but on the content of the "core" tag.
