Sorry - I use the Buzz Tools line of software i.e. Buzz Explore, Buzz Edit 3, and Buzz Word. I am able to change the size somewhat with Buzz Edit but I just looked and they have a program Buzz Size that will resize up to 200% while maintaining the same design density. I like the Buzz Tools line of software as it is very easy to use - most of the time I don't even need the User Manual to figure out how to do things. According to their website, Buzz Size is available for a free 21 day trial if you are interested.
