One of the key advantages of SumatraPDF over the other pdf readers is the ability to auto-reload the PDF when it has been modified externally (by other applications).
However, I found recently that this no longer works, but I’m not sure why. It used to work before.
Reproducing the error:
- Open file.pdf in SumatraPDF. (file.pdf is in my Desktop)
- Open file.pdf in Adobe Acrobat Pro.
- Highlight a line in file.pdf in Adobe Acrobat Pro (or just make some changes).
- Save (Ctrl+S) file.pdf in Adobe Acrobat Pro.
Then an error pops up, saying
and I am unable to save in Adobe Acrobat.
It (saving) only works if I close out of SumatraPDF first.
This seems to suggest that SumatraPDF is hogging on to the file.pdf, which is not supposed to be case. Normally, SumatraPDF auto-updates the file when it has been modified and saved externally.
Also, note that
ReloadModifiedDocuments = true
is set in my advanced options.
Any help will be appreciated.
I am on Windows 10, 64 bit, running Sumatra v3.1.2.
