Position off in Repetier Host?

[dpmacri]

When I add an object into Repetier host, it's almost always off the edge of the print bed -- something like X=90, Y=90 or so. I have to end up manually changing X and Y to get the object into the center of the print area. I'm using the Mac version of RH (which is 0.56). Anyone else seeing this problem? I suspect I have dimensions setup incorrectly somewhere, but I played with a few things and couldn't figure it out. Also, during printing, RH only shows one quarter of what's being printed. It looks like it's just the "positive" quadrant, with nothing in the -X or -Y regions (assuming 0,0 is at the center) being shown. Is that a known issue?
