Changes since 1.2.3 to 1.6.1 /IF

Hello,

I have a problem with the following command line:

It is supposed to convert the document without user intervention.

"/IF"“C:/Temp/doc.ps” /OF""C:/Temp/doc.pdf"

in 1.2.3 it works fine.
But next versions include : 1.6.1, It show the user the window for saving manually the pdf.

What I have to do different. I have read manuals and I do not see any difference.

Thanks.
Alfonso
