I have only ever used the command line for lit2lrf.exe
I thought the above mention of a "check box" and "dialog window" was referring to an ability to do the conversion using the Libprs500 GUI.
I thought this because I have never seen the "check box" nor "dialog window" referred to.
From what you are inferring there is no GUI ability for conversion.
What was he referring to then?
Sorry upfront I am a newbie at this (from days ago not weeks)
