Has anyone experienced this problem on both the 1.2 beta and official 1.2 update on a Mac running Leopard. I have just downloaded the 1.2 update and installed it. There is a GUI redraw problem when switching between VS or Hybrid back to Prophet 5. This happens in Standalone and when loaded as a VST instrument. All the knobs have strange colours and they can't be adjusted. sometimes I have to change back a few times before it will work and sometimes I have to close then re-open the app before everything appears normal again. It is always OK when it is first loaded.
