Well, I just checked and found out that one of hte versions i was running was 64 bit and the other was 32 bit,

So I deleted and reinstalled the software as 64 bit, but i still have the problem  When I start typing in a name of a record in the combo box, you can actually see what i'm typing in for the first 60 or so records, but after that, the combo box goes blank.  I can drop down in the combo box and see the records, and if i highlight the one I want, it will go to that record. However, if I change the sort order of the combo box, it will let me see the first 60 or so records, but nothing past that!  UGH!!!!
