Cryptic enough title for this post?

I have recently upgraded to AutoCAD MEP 2008 (no Express Tools). And I need to find out if there is a setting or Sysvar that corrects the text in a block to read correctly after you mirror a block?

What happens is, I mirror a block with text in it and it is now backwards. It happens in a block with text or a block with attributes.

In previous versions AutoCAD 2004 & 2007 it flipped without a problem but they were machines that were previously set up by others.

Any ideas?
