Center marks not in center!

I have an annoying problem: I can't get the center mark to bein the center of a slot! I had a perfect drawing, now, after aminor dimension change, all my sections views don't display thecenter mark in the center. Please see image below.

No matter what I select, the center mark snaps off-center. I trieda few things like changing the display to shaded with edges, movingmy section line to force a view update, and even tried differentslot center marks to no avail.

Thanks for your help,
