    "Replacing Font" CPU 100%


      Hey folks,


      Acrobat Pro 10.1.4


      End user changes the color of two words, a very minor edit, and hits Save.  Acrobat displays message "Replacing Font", CPU goes to 100%, and the document takes 55 seconds to save.


      Anyone seen or solved this problem before?


      Thanks much,

          We need much more information to speculate why this happened. But changing anything in a pdf file is not necessarily minor. We always recommend recreating the pdf file from original documents. Editing a pdf, can effect the embeding of the font used in the document. It may have been saved as a font subset, but now it may have to have the full font embedded. Never edit a pdf if it can be avoided.

            Thanks Michael for the reply.  Unfortunately, our end user MUST edit this PDF and many others on a regular basis.  They are creating content within Acrobat. 


            What other information would be useful to diagnose this problem?  How can I determine if the font is saved as a font subset?  I am a network administrator, and not an Acrobat specialist or expert, but I can research and gather the necessary information.

              I am having this exact same problem in our environment. We recently migrated from WinXP to Win7 and for the most part the problem went away, but one particular Acrobat X user is still having the problem.
