angle dimensions don't work worth a crap....

angle dimensions are fine (sometimes) when i first place the dimension. but as soon as you move it, it goes to complete crap.

before moving dimension:

 

after trying to move dimension all my lines disappear:

 

i have to explode my angle dimensions to get them to show correctly which is ridiculous.

am i doing something wrong?

 

EDIT:

on a side note that's related, i also think i shouldn't have to explode a dimension just to get the text and leader to go to the opposite side. i want the text of the dimension to go to the bottom and to the right, not the bottom and left. i have found getting it to go to the bottom and to the right is impossible without exploding the dimension and manually moving the lines and dimension text.

this is exactly what i want:

not this:

and not this, this was done by "moving text with leader". this sucks because there's no snap to keep the lines perpendicular, and the line going through the middle drives me nuts:
