Missing dimension lines

[Tinmuk]

I have a template IDW that i use for bearings. When I opened it today I noticed that two of the dimension lines were missing.  The dimension and arrows are there.  I tried deleting them are recreating them with the same result.

The interesting thing is, when I created the dim above the part it was fine,  when I dragged it below the part the lines went away. After that no matter were I moved it the lines would not reappear.

I installed SP1 a while ago and just now installed the update to SP1 (DL20857064.zip). It did not fix the problem.

Any ideas on what is causing this?

Ok, I figured it out.  For some reason a text box will hide extension lines but not anything else in a drawing view. The text box defaulted to the entire width of the drawing and hid the extension lines.  Once I resized the box evething was fine.
