Re: Running two silmultaneous instances of mathematica using a command line

Instead of launching the Mathematica.exe binary in the installation 
directory, launch the Mathematica.exe binary in 
SystemFiles\FrontEnd\Binaries\Windows.  The former is a simple launcher 
program which tries its hardest to redirect requests for opening notebooks 
to running copies of the user interface.  The latter is the user interface 
binary itself.
