Oh I had that problem with Mousepad when I was playing Zy-el on D2Loader.
In your D2 Shortcut pointing to your D2loader. Try adding this to the end of the target:
Code:
"C:\Program Files\Diablo II\game.exe" -title "Diablo II"
Some maphacks check for not only the version you have, but
also if the window is literally called "Diablo II". I talked about it in the Zy-el install guide.
By default, D2loader loads up the date and time you ran the executable into your window bar.
