[HARDWARE PROBLEM] 600d won't end a bulb exp.

[imagecatcher]

I had a previous problem where I had no menus, this was fixed via a work around hack autoexec file (thanks Alex). I got one session of Bulb exposures before it has now failed. Upon shutter being triggered the count up screen appears but when the trigger or cable is releaseed the shutter continues to  (presumably) stay open and the count continues. No buttons will stop it. I must turn the camera off but then the LED stays on forcing me to remove the battery. This happens regardless on the bulb method used ie ML or Canon.
Since I installed ML to do Bulb this is frustrating.
Thanks

As stated before, you need to fix your shutter button first.

Anyone aware of a youtube  clip to disassemble a 600d? I have pulled many canon P&s apart but not a dslr.
Alex, it does it even if I dont use the trigger...short the cable release port. I'd hate to open it up and it wasnt a hardware issue alone.
I do appreciate you comments.
