DEP violation when configuring MIDI controller.

Trying to remove and M-Audio Keyboard Controller (setting entry to none) on a PC with PT 12.3.1 and getting this.

Stuck in an access violation loop after responding to error, so have to kill PT process to get out. Deleted prefs and controller gone - everything OK, just reporting possible bug.
