I just purchased the game. Online, I upgraded it to v1.03. I ran the tutorial.
A little ways into the tutorial, it tells me to zoom in/out with my mouse wheel. But this laptop does not have a built-in mouse wheel. I can't find any way to go forward in the tutorial without accomplishing this task, so I'm kind of screwed unless I can get some good advice here. (I checked the mouse settings, and there also is no mouse wheel emulation.)
FWIW, this is a Compaq (HP) nc6400 laptop.
Sadly, I bought this game to keep me entertained all day while I'm waiting on a loved one's operation to finish.
