It’s a 10.6.8 issue. It is highly unlikely Steinberg will be willing to fix this. You basically have two choices:
- Live with the issue on 10.6.8.
- Move on to 10.8 and start searching for 64 bit plug-ins updates (or substitutes) to replace the 32 bit plug-ins that worked in 10.6.8.
This has been discussed in another thread somewhere.
