Sorry to bother you folks again but I'm having a problem here.
The game loaded from the disc with no problem and the game played find, I then tried to save.
When I got onto the main menu my cursor became of jittery, going all over the page. Great difficuly in quitting. I've look at their webpage but no mention of this problem.
Is there a patch somewhere to fix this?

I don't know of a patch. If there was one it would be on the developer's website.

Does the problem repeat every time you play the game and try to save?

If it does, try emailing the developer. He's very good about giving support for his games. You can find his email on the support page
