"PDF already open" warning when exporting PDF.

Idea created by rmangan on Apr 19, 2011
    Would it be possible to warn us that an existing PDF is open BEFORE going through the whole PDF export process? I export a large number of .mxd's to PDF daily, and this pops up quite a bit. Currently ArcMap creates the PDF, and if it is already open, it just abandonds the whole endeavour. Can we get a warning at the beginning of the export process?

    Or  "PDF is already open, Save PDF as...?"
    Or "PDF is already open on USERXXXXX, Save as?"
