Scaling issues are an ongoing problem sadly :(.
As for the top right thing, its been mentioned in comments here somewhere before, I can't remember if someone had a good solution though.
Thanks for you reply! I work through them not to worry. On a large screen everything seems to work ok. With regards to the scrolling. Mouse over the game itself doesn't allow you to scroll. But once the mouse pointer is over the background (?) of the website next to the active frame with the game (sorry don't know what that is called), the scrolling does work. Gosh I hope this makes sense...
