I use Texmaker in windows. I have used it for a while now without any problem, but recently the preview doesn't work anymore. When I click the "show PDF" button, it creates a new window that I can see in the task bar but cannot display. No error message, and the PDF is correctly created (I can open it with Adobe).
Of course I know I have to save my code and compile it beforehand, and like I say the PDF file is actually correctly created. This is very annoying, and I would very much appreciate your help on this.
options-->configure--> Commands-->pdfviewer--> both 'Built-in-viewer' and 'embed'?. Hope you have Latest TeXmaker 3.5.2 version installed. Of course there is no problem with old version as well. – texenthusiast Mar 4 at 21:35
