Halion one showing black square

When I go to the preset box in Halion one Im getting a black square covering the categories-is anyone else having the same problem? Im on the latest version of 6.5 and Mountain Lion 10.8.3

No problem here, but I’m not using Mac OS X 10.8. Can you see all your HALion Sonic SE presets? Just the categories field is black?

Can you try to trash preferences (make backup, before you delete it).
