I have an intermittent problem when printing Word documents as PDFs. I am using Windows 7 Professional, Adobe Acrobat X Pro, and Word 2010. This problem started occuring only very recently; previously I was able to print Word documents as PDFs without issue. The current problem is that about half of the time that I attempt to print as Adobe PDF, I do not receive a prompt for the filename and location of my PDF document. Instead, a tooltip bubble pops up in on my system tray with the Adobe symbol, telling me something to the effect of "your PDF has been created as k3r5pt.tmp." The other half of the time I receive the normal prompt to save my file. It does not appear to be specific to certain documents, as after this problem occurs I try again with the same document (after changing nothing) and it prints normally.
I have checked my preferences by going to Devices and Printers->Adobe PDF->Printing Preferences->Adobe PDF Settings and choosing "Prompt for Adobe PDF filename" in the Adobe PDF Output Folder drop-down menu. This has always been the setting and it still is. I am not certain where these .tmp files are being sent to or why they are being created at all. Any help you can provide would be appreciated so that I can print my PDFs successfully every time.
