Auto mode problem - Githubissues

I have been trying unsuccessfully to get Auto mode to work in Ardupilot APM1 
for past two weeks. Now I really need some help.

In the Ardupilotmega Mission Planner, I setup and loaded into APM1 a simple 
waypoint track consisting of home and 4 waypoints. Then I set Auto mode to 
radio channel 5. Before flying, I stabilised the plane and waited for APM1 
gypos and GPS to set. I also confirmed Auto mode on in the APM Planner Flight 
Data HUD screen. 

Then I launched the plane. I tested first that stabilize mode was working fine. 
Then I switch to Auto mode and the following behavior happened during various 
flights:
1. Plane immediate tracked back to launch point and circled overhead forever.
2. Plane increased throttle and went off in one direction at high speed.
3. Plane circled at its current location once, then spiraled down to the 
ground. (Need to disengage Auto mode fast.)
4. Plane flew the waypoints track once, then went back to launch point and 
circled forever. (Only happened twice!)

The following outputs from the ArdupilotMega MAVLink window: 
(sorry - can't send the attachments here due to quota exceeded)

(a) When I set Auto Mode in Radio Channel 5:
    - "setparam 'FLTMODE5' = '10' sysid 1 compid 1

(b) But when I flicked the switch to Auto mode, the following appears:
    PM Nav command index updated to #1
    PM Executing command ID #16
    PM Non-Nav command ID updated to #255
    (I don't see this messages in other modes)

Appreciate your help!
