I have Acrobat 10 Pro configured as the viewer for PDF-Tex using the standard settings. This setup usually works, but sometimes after working for a long time, opening other files in Acrobat, etc. TeXnicCenter appears to lose the ability to send instructions to Acrobat.
This first appears as a compile error: cannot write on file which is open.
After closing the file, the PDF is complied correctly, but then I receive an error when TeXnicCenter tries to tell Acrobat to open the PDF.
