This all of a sudden started happening to me in 2010, and now is suddenly doing it in 2011 as well.  When I add a dimension, the text disappears.  You can still click it, if you remember where you placed the text, but it is invisible.  I have to right click the dimension and go display options show parenthesis on each dimension, just so I know where I can double click to change the value later.  Then it shows the parenthesis, but the text is still invisible.

This is infuriating, as it makes modifying sketches much more difficult then it should be.  How can I fix this?  I am using an ATI FireGL v3300 on the recommended 8.583 driver.

Thanks for the help!
