I use 800x600.
I hope it isn't changed, I would have all these scroll bars on the bottom taking up the screen. It would be quite annoying. I hope you don't do it. However much say I have. -_-;
I have switched it to a higher resolution before and I do know what you are looking at Wade, but when I noticed how much smaller the flash videos were I found putting myself back to 800x600.
It does have its downsides when there is a flash that is very long/wide and then the flash box is scrollable and is annoying, that isn't all that common though.
