<DIV>I had this happen on a brand new BB Mason and Hamlin not so long ago.&n=
bsp;
I raised the glide bolts, and it slipped right out. They'd been cranke=
d
WAY down, though I couldn't figure out why. The keyframe was
up about 1-16 inch higher than it should have been. </DIV>

<DIV>I hope this helps,</DIV>
