Is there a particular reason why the tools menu seems to only allow .exe files to be used as the command?
I have a Java program that I want to run and I normally use a .bat file to set the required environment, rather than using global environment settings.
However the Tools / Customize menu option didn't seem to like specifying a .bat file.
In his particular instance I can use the raw command line as there is no special environment to setup.
But there are other Java programs that I can't run without a .bat file as they use the same environment variables, but with different values, so I can't set them globally.
