borntobesting: With Maxthon everyone has letter box as you call it.At least an inch black edge on each side. Comodo Dragon does not.It fills the entire screen side to side
I use Maxthon 3 some (IE some also), and with Maxthon and it fills my 27 inch screen complete side to side, however, i do have an inch at top and bottom. I'm running XP. I've tried it on Windows 7 on my laptop, and it does have black space on each side. So, the operating system has something to do with how the display is handled.
