Cheryl,  Have you submitted this to tech support ?   I am getting a similar situation depending on the character height used in a standard text grid line chart.  I thought it was just a result of the bug with Chief's Chief Blueprint font but experimenting with other fonts it seems to be a more general problem effecting even standard fonts like Arial.   Here is a screen shot of a 18" character height when 6" or 72" are fine in the same setup.
