I am using wkhtmltopdf.exe for converting html to pdf using python. The pop-up window of wkhtmltopdf.exe making it very difficult for me to work on any other things while running it. I have to convert around 200K+ files and have to work on something else simultaneously. But its really not letting me to work on anything else.

Is there a way of stopping this or running it in background? I really appreciate your help.

PS....
