I just discovered that Finale 2011 is available for pre-order. From the read-me file about Fin2011 you can read:
Human Playback
Human Playback no longer causes unexpected CC11 data.
Errors regarding inserting keyswitches have been resolved.
Dynamics now play back correctly with Garritan Sound Effects.
The interpretation of trill accidentals has been improved.
Additional instruments including harpsichord and accordion are now supported.
I don't know if this will solve any Finale/VSL problems discussed in this thread but one can always hope... ;-)
