I have that prob alot as well.. I would assume one could remove the pin in the button for the lock and the prob would be gone..
Love to do it myself but I'd like the lock for locking it on the go.
I would settle with a wider open track.. it must be real norrow as it is for the pin.. the slightest movement and it's locked.
I'd also like a little longer throw in the button as well. Should be able to just shorten the button end for that.
As it is there's really not much difference on or off.. it's hard to tell either way.
Those changes sound perfect for me but its nothing I can do myself.
