Could not load DAT files when launched outside of its directory (even if in PATH)

[Yrouel]

I copied MICROWEB.EXE and its support DAT files inside the mTCP directory (seems neater) which is in the PATH, but when I try to launch MicroWeb from any other directory it closes after the video mode menu with the error "Could not load DEFAULT.DAT" (or any other required dat file).

If I launch MicroWeb from within mTCP it works as expected
