First thing you need to do is to turn the option on in your settings. To do this, find your Neverwinter Nights directory and locate the file nwnplayer.ini You can open this file in any text editor to edit it (for example in Notepad). 1. Open up your nwn.ini file in a text editor. 2. Under the [Display Options], make sure your setting for the game resolution is less than your desktop setting. For example, if you run your desktop at 1024x768, then change this to Width=800 and Height=600. If you don't make it less, it won't work. 4. Change the FullScreen from 1 to 0, like this FullScreen=0
