I have been having the same problem with a 64 bit machine running Windows 8.1 with a very high resolution. By degrading the resolution, and reducing the scaling to 100% I can reproduce what I had on an XP 32 bit machine. Seeing how the majority of members of our Genealogical Society members are over 50 (I'm being kind) it amazes me that the scaling issue has not been addressed by the publisher. Caveat Emptor! I will look for another program that is more responsive to those whose visual acuity is diminished.
