I've just started using Texmaker and am using it on a fairly large screen, large enough that it would be useful for me to be able to type my document and have the output PDF file next to it. I know it's possible as the setups at my university do exactly that. However, when I click the arrow next to "build pdf" it opens the PDF in a separate window. I've found a similar question on here to what I'm asking, but it refers to a preferences window that I simple cannot find anywhere.
Any help would be appreciated.
