Unfortunately, the application does not run without the .Net framework and the installer is too heavy for my free hosting service. If anyone knows any place I can place a 3.5 Mb file for free download, please let me know.
For those of you interested in the code, the project is available at the same place.
Lastly, there was a bug, which probably went unnoticed, in the older DOS version. That has been fixed in both versions.
