Hi tsmpaul,
Welcome back to Dungeon Craft!
There aren't any threads about this, because I think everybody but myself are working at 640x480.
But, never fear, it's pretty easy to switch.
You may or may not need to do all of the steps below if you've been trying to do this, but I wanted to list all the steps in case someone else needed it. Plus, I'm going to add this to the F.A.Q. and maybe the Wiki. (You can find these following the links in my sig.)
If you are in need of art for this resolution, I have some at my website (again, just check my sig) as well as the NPC download pack available at SourceForge.
How to increase resolution for Dungeon Craft (DC)
1.) Go to SourceForge and download the 1024x768 resolution art pack. It's in the 1.0.0.0 section and is called DCart1024.exe. Install this into your DC directory. As well as containing the art files you will need to start at this resolution, it also contains the important config.txt file which DC uses to run the editor at the proper resolution.

2.) Navigate to the new folder, which should be someplace like C:\Program Files\
DungeonCraft\DefaultArt\1024 (substitute the appropriate drive letter and directories as necessary). Open the config.txt file in the text editor of your choice. You need to modify lines 11 through 15, substituting "DungeonCraft" for "UAF" in the directory paths, or if easier cut and paste the following.
Install_Dir = C:\PROGRA~1\DungeonCraft
Default_Resources = C:\PROGRA~1\DungeonCraft\DefaultArt\1024
Default_Resources2 = C:\PROGRA~1\DungeonCraft\DefaultArt
CommonCharFolder = C:\PROGRA~1\DungeonCraft\CharSave
Game_Exec = C:\PROGRA~1\DungeonCraft\UAFWin\UAFWin.exe
Note: I will be updating this package very soon, so the last part of this step, editing the config.txt file, may be obsolete as of your reading this.
3.) Open DC and choose Mode from the top menu. Choose Editor Options. In trhe box that pops up, choose a resolution that is equal to or larger than the resolution you want your design to be at. You will need to close and restart the editor for the changes to take place.
4.) Open DC if you have not already done so. If you are not working in full screen mode, you may need to resize your window to see everything. Go to Mode in the upper menu and choose Configure Game Screen Res. Click OK on the warning box that pops up. It is just informing you that you cannot choose 800x600 resolution as the editor could not find a config file for it. Select 1024x768 and click Change Game Res. Notice that there is a checkbox to change the configuration of the currently selected design. Only check this if you witsh to change resolutions of that design as well. Click OK on the pop-up box and then close and restart DC.
5.) The walls will not display correctly. Don't worry, you didn't do anything wrong.
If you have changed the resolution for the currently selected design, you will need to open the wall editor and replace the walls with those you just downloaded. Otherwise, it's time to create a new design. Select File from the top menu and choose New... Type the name of your design in the upper box and click OK. Now, go back to File and select Open... Choose your new design, click OK and you are ready to go. Notice that the new art is preloaded for you.
