T-Guitar: very difficult to select patterns

I bought T-Guitar a few months ago and I am learning how to use it. There are no tutorials but I found a demo by Dom on YouTube. He makes it look easy but I have to work at it. I noticed that Dom has a different menu than me when it comes to selecting a pattern. I only have a very long list that I have to scroll through with the arrow keys (the mouse will not scroll) and it is very awkward to work with.

Does Dom have a more recent copy? Should I reinstall and hope that the convenient pattern menu will match that of Dom?
