One would think this is set in X and Y within the mod, and was positioned within a larger resolution than 1680x1050... from Dialog Control - biwiki Positions and dimensions (x, y, w, h) aswell as font sizes are relative to the screen (and not pixel values), normally ranging from 0.0 to 1.0; 0.0 means 0% of the screen width (e.g. the left side of the screen in the context of x or y, or 0% length in the context of width and height). This makes font sizes usually a very small number (~0.02). This percentage is only based on the standard 4:3 screen area. A dialog will look the same for all users, regardless of their monitor's aspect ratio, as long as their aspect ratio is set correctly for their monitor in the display options panel. This is only likely to be a problem, should you be intentionally trying to fill the whole screen with a dialog and the user has a non-4:3 monitor. In all other situations, this behaviour is likely to be to your benefit, as you don't have to worry about users with different setups. Keep this in mind. You can set your positions and dimension outside of 0-1 if you wish. For the most part though, it's not recommended as parts of your dialog will be drawn outside the standard 4:3 screen area. This means the majority of users could not access the items outside this area. One practical application for that though, is that it lets you make a solid background that blocks out the screen for all users regardless of their monitor's screen aspect ratio. This can be done by setting a panel's position and dimensions to "X = -1; Y = -1; W = 3; h = 3".
