Help with decimal in EASYAcct

I am working in EasyAcct Professional 2007/2008. I am entering data into the Transaction Data Entry screen. When I try to enter an amount like 123.45, I get 12.345,00 (12,345.00).Can someone please tell me how I can enter an amount for 123.45? When I enter 2.34, the program displays it correctly as 2,34. I am not sure why it is not displaying it correctly for values in the hundreds. Please help! Thanks.
