I'm having trouble getting Visio to convert a drawing to a PDF. If in Visio I click on the Adobe PDF tab and select "Convert to PDF" a progress bar opens and goes quickly to about 3/4 done, then hangs. Task Manager shows no CPU activity by either Visio or Acrobat. I tried the File / Print and selected PDF with same results. If I open Acrobat and open the Visio file and ask it to convert to PDF, it launches Visio but then it hangs. Once again, I see no CPU activity by either after the hang. This is Visio 2007 and Acrobat 8.1 running under Vista. I applied current service to both Visio and Acrobat. I sent the Visio file to a colleague running XP and he converted it to PDF in a heartbeat. Nothing obvious shows up in the Vista event logs. I can convert Word documents to PDF with no problems. Any theories? Thanks, /rich
