SH3 Mission Editor Black if D3D9.dll present
 

Any idea why I cannot use the mission editor if D3D9.dll is in the folder?

If its there I just end up with a black map, in the middle of the editor. If I rename it the editor seems to work. Any idea why?

It is a bit dependent upon the WS you are using. In some of them, you can run the ME, but all circles are ovals, and it will crash at times. It is best to do the ME without a WS mod, and as you found, removing the directx dll and ini files (or renaming them). You gain nothing in the ME with a WS mod. The window is still the same size...
