Ok. I had slowed down for something or another and was in 2nd. I then started to accelerate, about 3/4 throttle. When I tried to shift to 3rd, the shifter abruptly popped out and made a very loud 'pop' sound. When I let the clutch out it was still in gear even though the shifter was in the neutral position. I hope that is enough detail for some responses. Thanks.
