It's a bug. The Data Grid isn't setting alignment when creating the  
headers from scratch.

You can either set the alignment each time your program opens or add a  
1 line fix to the Data Grid behavior script. Instructions follow.

======
1) Open Script
======

edit script of btn "Data Grid" of stack "revdatagridlibrary"

======
2) Locate _table.CreateHeaders command
======


======
3) Add line to _table.CreateHeaders command
======


             set the dgTooltip of theGroup to theColsA[theColumn] 
["tooltip"]
             set the dgHilite of theGroup to theColumn is  
sortByThisColumn
             #####
             ## ADD FOLLOWING LINE
            #####
             set the dgAlignment of theGroup to theColsA[theColumn] 
["header"]["alignment"]
             lock messages
         end if
     end repeat
end _table.CreateHeaders

======
4) save revDataGridLibrary stack
======

In message box execute:

save stack "revDataGridLibrary"
