Font size in text boxes on PDF form

autoFiller.ImportDataTable(ds.Tables(0))

That line saves a lot of coding!  Everything works great, except that the font size of the resulting data is very small.  If you open the PDF in Acro reader you can type in the text boxes and the font size is normal.  But when you do the import, everything is small.  Why is this happening?  What can I do to prevent this? 

I have question in to the original form designer to see how the set up the text boxes, but I don't see why the import would be any different than the font used when typing on screen.

Thanks
