Windowed mode problem

First post here, I'm a regular at the GW2Guru. I registered because I needed help with something. While playing windowed mode, I get this weird bug that makes the right side of the screen look jumbled up. Here's a pic:

It's really weird. This shouldn't happen. Is it because of the widescreen? It's specially annoying because the game recognizes the image as if it was right. So, if I try to click "options" as it is, I still have to click where it would be if it wasn't giving me this problem.

Edit: Yeah, maybe I should have named the thread after the problem from the start.

Do you have a non-standard window size set in your target field for the game? I've seen that before when people try to use -w to window the game instead of picking a window resolution from the graphics dropdown options.

I guess I do, I resized it manually. Is there any way to play the game fullscreen window-mode? Or at least get to make it be default window sized again so I don't have the gaudy black bar?

Screen's resolution is 1366x768

Nope sorry, you won't be able to play it windowed properly at that particular resolution...you'll have to pick the closest one to your screen size from the dropdown options or you'll have to just play in full screen.

I'm on a laptop that is 1440x900 and I play it in 1024x768 so that I can see other windows while I play. IIRC there are 3-4 dropdown options in the Windowed Mode extended options.

Then it's strange, because when I go to the drop down box it just has the windowed mode option, doesn't give me any resolutions for it... Am I missing something? It's really strange. I can take a screenshot of my resolution options, if you want it.

Edit: Here it is:

if you are in windowed mode you should be able to adjust the window size by dragging the corner of the window ???
maybe its a windows 7 issue i still use xp lol

Yes,as N E D M said, you should be able to drag the corner of the window to re-size
Plus you might want to edit your screen shots to take out your email and character name...with that amount of information it wouldnt be hard to brute force your password!

do me a favor remove your email, doctor that photo please, hide your email and character name, MAINLY YOUR EMAIL

Have you tried pressing Alt-Enter (going fullscreen) and then back to windowed mode?

Okay, I'll be editing it then.

Also, yes, I've tried that, the bar is still there, mainly because it window-modes back to the size I re-sized it too.
