X3e Prod MIDI controller problem

X3e Prod x64, Windows 8.1 x64, Akai MPD26 Preset = Generic 20
Set up MPD26 transport buttons via Controller/Surface Properties as:

<< = Start/Stop Rewind
>> = Start/Stop Fast Forward

STOP = Stop With Now Marker
PLAY = Play/Pause

REC = Record

Everything works as expected with the exception of one case; press << and let run until it stops itself at the beginning of the project.  Clicking the toolbar >> now continues running instead of stopping when the mouse button is released.  Clicking << will get it to change directions, but it will continue until it reaches the beginning again no matter what is clicked.  << and >> continue operating this way until << on the MPD26 is pressed.

It appears that there is some missing logic in Sonar.  I believe if << is pressed, the action should be programmatically toggled off if allowed to stop on it's own at the beginning of the project, also handling the case where << is pressed when the transport is already at the beginning.

This is 100% repeatable with the MPD26.  I have not yet tried with a different controller.

Anybody got a minute or two to see if this happens with other hardware?  If it's an Akai quirk I still have time to return the MPD26.
