The application downloaded without a hitch ((TiBook/1 GHz PowerBook G4/1024 MB memory/OS 10.2.8) but the instructions are incomplete. I get as far as clicking on the empty circles and each time, I get a green blob. And I can see the pegs in the grid off to the right. Okay . . . now what? What do does one DO? How do I manipulate the blobs, or do whatever is to be done? I tried clicking, OPT + click, CNTRL + click, SHIFT + click, etc. but nothing happened. Please elaborate!
