Font Size Change During EDITANNOTATION

Hello,

I recently changed over computers from Windows XP to Windows 7 Professional, and am encountering a problem with the new installation of Draftsight that the previous version did not have.  When I go to edit text in a drawing, it will often change the text size when the edit box pops up, per the screenshots below.  

Does anyone know why I would have this problem only with the newest version of Draftsight (on a 64 bit machine)?  If it is relevant, my files were all originally saved as Autocad R14 files.
