-bmp Not Working?

So, a while ago I used the -bmp command line argument. It worked one gaming session. That's it. It's still in my properties but it's still not working. Any help?

When you create a shortcut to GW2, and then pin it to the task bar for instance, and then add "-bmp" to the first shortcut, the second one used in the task bar won't have that property, because they are two different shortcuts. The same goes if you have a shortcut in the Programs group and another one on the desktop - adding properties to one don't automatically apply them to the second.

Simply remove all shortcuts except one, add any properties you want, then you can pin it or otherwise copy it.

I have the opposite problem, all my ss were saving .jpg, now they're saving .bmp! Where on earth is this toggling itself?
