Great!  I'm glad I could help, and I'm glad you stuck it out.

While I think it's a bit harder to get set up with MinGW and wxwindows,
that it would be to use VC (once Faizan's project files are in place,
etc), I think it's better, because then changes and contributions you
make are helpful for people on platforms other than Windows.

Bill still doesn't have 100% of the market yet!
