Fred has been trying to find the cause of this elusive bug for a long time.
You are correct that upon entering manual mode, the first jog move is slow. I
forget whether you have to reverse direction to get the normal jog speed back
or whether it's just the second move regardless of direction. I also can't
remember if it's just the first move that's slow, or if the first move for
each axis is slow. Once you clear this condition, and jog speeds are normal,
you can "reset" the bug by switching to AUTO or MDI mode and then returning
to MANUAL mode.
