I was working with Latex normally ( I use miktex and texmaker). Usually I used to click on quickbuild, then directly and automatically the pdf open in an external window. TOday, suddenly I lost this property, I open my Latex file and try quickbuild, then no pdf is open, and even I am unable to see the new pdf until I opened it from the folder where the latex file is presented.
I tried option-->configure-->pdfviewer--> embeded. In this case I see teh pdf in the same window beside the latex file. I would liek to see the pdf on an external window.
Can anyone help me solve this problem. Thank you in advabce.
