Has anyone seen a problem with ACT under Sonar X2a where ACT assignments under ACT are not properly recalled after restarting Sonar.

I can save my preset configuration, then load a new preset to totally changes things, then recall my original preset - and the ACT assignments seem to works.  When I restart Sonar however, I find that some of my ACT assignments are not being restored properly from my presets - some of these are missing, or are reassigned to the incorrect cell in the ACT matrix (I'm using the ACT Generic Midi controller).  As far as I can tell, I think the MIDI assignments are still ok..

I have Sonar X2a installed.  (which is an upgrate to X2 from X1.3 from 8.3).
