You're not alone. I tend to do the same thing. But I've yet to use Windows on a very high-resolution display. I doubt I would want my browser window full-screen on a display with 1600 pixels or more in width.Strangely, I like putting windows in full-screen mode while using Windows. I like each window to fill up the screen. Conversely, I hate full screen windows on any of my Macs. I'd much rather have them be just the right size to have numerous windows on my screen. I can't explain it. I just switch "modes" when I have the operating system in front of me (and yes, that includes parallels).
