Dimension Texts not on dimension lines

Struggling to learn AutoCAD 2010, its not anything like 2007. I'm inserting dimensions and the tics keep coming out huge and not on the dimension line, in fact there's one on either side 20 ft out. If I change the drawing scale in the tab at a the bottom the tics get smaller and closer in, but they are still off the dimension string by a long shot.

Can figure out what is causing this?

Any tips for trouble shooting?

Are you in Model Space or Paper Space? What do you have set up in your Dimension style?

Post the file here.

In model space.

Could your tics be a block? If so, where is the insertion point?
