In the previous version fonts could be increased and decreased in size by controls in the menu bar

In the past version you allowed for the inclusion of controls for text sizing in the active window of the MacSword. The newer version of your software allows for sizing. However, I am not able to control the sizing as before in the newer version. Something has been changed because the size specified in the drop down menu does not correspond to the size viewed on the screen. For example, right now to get a 12 Pt. size in the screen I have to go to the maximum size allowed for in your drop down Font Size control, which I believe is 28 Pt. What has changed on this new version that does not work as before? Thanks for your answer.
