Yep, I was afraid of that.  Problem is, I was very careful (I THOUGHT) with 
all of the alignment steps.  Oh..... #$%^@, I think I know what I 
did....  If I did what I think I did, it will be a big oops and a very 
sheepish,-head-ducked,-slink-away-into-a-dark-corner-moment.

I'll do the alignment all over again.  If I don't post again for another 
year or two, you'll know I was too embarrassed to show up here again....
