I have a user with an Excel 2013 spreadsheet that contains file hyperlinks. Every other file type will load fine when she selects it, but whenever she clicks on a PDF link, it will hang for several minutes and eventually crash Excel. However, if Acrobat is open prior to opening the link, it will open without a problem. I tried reinstalling Acrobat but did not have an effect. Has anyone dealt with this issue before? It has to be localized to her system because she is one of several other users in her division and they don't have this problem. She uses Acrobat XI.
