Math error?

I'll take that back...even though the final Deduction screen added the $600 charitable deduction (for a total of $27050), when I get to the final review the number reverts back to $26,528.  And yet, when I review Form 1040 the $600 is there and the total is correct.  It gives me ZERO confidence when I see the numbers bounce back and forth like this.  I've never used tax SW this buggy.

Here's another fine feature...on my Windows desktop version, when I exit the program, it decides to restart by itself.  Once I had to close it three times before it would stay dead.
