Scenarios provided by the game

[Ratel]

The game graphics itself seem ok, but the scrolling is now slow and jerky and the buttons for preferences and others is a mix of several colors and you have to look close and strain a bit to read what the buttons are. It wasn't like that with XP, but is with 7.

Must be something wrong with some settings somewhere.
I run both winSPWW2 and winSPMBT on Win7 without any problems, full screen.
I am not a tech specialist, maybe some of the other guys an help, however, one thing I can suggest is to install it on C: as a new folder, not within Program Files. I remember having to do something like that myself at the beginning. If that does not work, then try to run the game via the Game Options file instead of the Exe file.
Maybe I am talking cr@p but it is around midnight on my side and I just got back from a work party where we had no shortage of wine and whiskey. LOL

I always install to custom folder too, and have had no colour problems. Does it not say to change the directory on the install instructions, I know one of the games I play does.

Make sure you are running the game in windowed mode with screen size set to "desktop" - this cures the jerky scrolling and a bunch of other display problems
