I noticed on the LUA page that you cant scroll down through the script. There are no scroll bars and when the cursor moves off the page it does scroll down automatically. Page up and down buttons dont affect it either.

I have the same problem, here's what it looks like:

I think you can use the down arrow (I think it follows the cursor) and it will scroll, or I believe the mousewheel and trackpad scrolling work.

Nope, the down arrow doesn't work. It just moves the cursor down and hides it.....

Mousepad scrolling doesn't work if the computer doesn't support it..... And it would be hard to use a mouse while sitting in the car...... Though admittedly the scroll wheel should work fine when sitting in a car....

According to this it supports scrolling: http://docs.esupport.sony.com/pc/SVT1111_1311_series/EN/contents/03/04/01/01.html It doesn't mention which model though.
