Auto Save Problem

I setup Auto Save to a folder on a mapped drive. The mapped drive is shared and available. Intermittently the PDF File never gets to the folder. Sometimes it takes three attempts for the file to appear. No popup errors are seen. Running the latest version 1.1.0 and I tried the 9.7 version. Running on a Windows XP Machine with PDFCREATOR loaded locally. The auto save folder is on a Windows 2003 server. Any suggestions would be apprciated.
