Ricoh GR-1 problem

Howdy folks,

My trusty GR-1 has developed an annoying problem...it quite often
loses the focus and exposure lock when i press the shutter release
button all the way down (from the half way position).
Its as if i took my finger off the button. Sometimes it will do this 3
or 4 times before it works properly.
This is pretty annoying as it has caused me to miss out on some good
shots.

Have any of you GR-1 owners out there experienced the same thing?
I don't imagine theres a quick fix for this, i'm just looking for more
info on it.


thanks for your time
