Problem solved. Noel, I went to the tracks drop down list and found the merge option as you suggested and discovered that the "merge audio to mono" function was selected. I had to uncheck it and merge the files before it would accept the change. Once I did that I was able to export to a stereo wave file. Thanks for your help. I suppose I will contact PG support and let them know although they never got back to me.
Regards,
Rich
