The problem with Windows is that only command line applications have access to
stdout. And command line applications automatically create and show their own
command window (DOS prompt to many people) when they are run from anywhere but
inside cmd.exe (which has its own command window). So LDView cannot produce any
output on stdout.
Microsoft's OFFICIAL solution to this problem is to create a wrapper program,
rename the .exe file to .com, and then stick that alongside the original .exe
program (I kid you not). (The command interpreter finds .com files before .exe
files, so the .com file will get run instead of the .exe, and the fact that it's
really a .exe file that has been renamed to .com is ignored.)
I have done some work on an LDView.com wrapper for LDView that would allow
stdout to work. It's not in a usable state, though.
