Well, looking at all the logs, RR is receiving both the "NAVxxx" cmds. And RRExt is executing them as shown by the "Red/Raise Vol:" lines in its debug log.
Next easy step would be to go back to something more simpler..
#1 Unreg and Move all other PI's except for SkinTool & RRExt
#2 Turn off all other RRExt features(xx_Enable=false) that are not needed for this, which is just about all of em.
#3 Go thru steps again.
#4 See if issue is still there
#5 If #4=Yes Then Re-Post debug logs from that trial.
Worse case, I'll have to get you a custom RR,RRExt & FoobarRR.dll with extra debugging to get to locate the issue..
