Running latex-preview manipulates and then deletes the pdf created by latex. If skim is open as pdf-viewer the pdf gets sliced into the images created by latex-preview. Running latex again doesn't update the pdf-view in skim. The problem of vanishing the pdf file is already listed on the package homepage https://www.gnu.org/software/auctex/manual/preview-latex.html under B.5.2 and B.5.3. There is mentioned as an explanation that Preview-latex uses the filename of the original output file for the creation of preview images. But neither on that homepage nor somewhere else I was able to find a solution in order to prevent this. So how can I prevent preview-latex to manipulate and delete the pdf file?
