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.
