I have created a few LyX files using 2.3.1 that are identical in their document settings, and yet, when I hit Ctrl + R, some files are processed to completion and throw up a pdf in Acrobat Reader DC, while others are processed to completion and do not appear in Acrobat. When a pdf file is not generated, I get the following messages at the end:
22:16:29.114: output file: C:/Users/UserName/AppData/Local/Temp/lyx_tmpdir.ljKjwYrYaULg/lyx_tmpbuf2/FileName.tex 22:16:29.115: 22:16:29.161: pdfview "FileName.pdf" 22:16:29.163: Successful preview of format: PDF (pdflatex)
I can if I wish, to to File > Export > Export As ... and save a pdf file, but I would prefer that it come up automatically in Acrobat. Has anyone experienced this problem? If so, what is the solution?
Thanks in advance
