Hi Dan,

        I replaced the sliding door rollers and the rear hinge.  When done my slider acted like yours.

I ended up needing to adjust the post in the back of the sliding door opening.  It catches the latch as it comes in from the back of the slider.  It is a round post that comes out of the Piller.  I used a wrench to loosen the bolt at the bottom.  I lowered mine a bit then tightened.  All working correctly now. 

Good luck.
