You can do this with the wscript.shell COM object:

Code:
alias runex {
  .comopen runex wscript.shell
  if (!$comerr) { .comclose runex $com(runex,run,3,bstr,$1-,int,0,bool,$false) }
}


This completely hides the window, it doesn't just minimise it.

As an added benefit, if you want the script to wait until the program has finished executing before continuing, change "bool,$false" to "bool,$true" smile
