Good deal, thanks! This is working for me.
My setup is:
Opera: Opera Mobile 1938 (cooked into ROM)
I'm using a custom ROM based on Alex's HTC WM6.1. I'm not sure which build this is, but it shouldn't be too hard to find.
So, I've got full screen to work (right click and choose the bottom option). But there's a bar on the bottom that's kind of annoying. Also has anyone figured out how to use flash games that are intended to work with a mouse?
