MS Word Starting When Starting Computer

I have Windows XP and MS Office XP (2003) loaded on my PC. Whenever I boot up the PC, 3 sessions of MS Word open - 2 sessions have a new (blank) document open, and the 3rd session just shows Word as being open (no new document).I went to Documents and Settings | Application Data | Microsoft | Word | Startup to see if there was anything in the folder prompting Word to open the 3 sessions. The folder was empty. I then clicked Start | Run | msconfig | Enter to see if Winword.exe is in the Startup folder. I thought I might see it in there 3 times – one for each of the Word sessions that are opening whenever I boot up the PC. Strangely enough, Winword.exe wasn’t in the Startup folder at all – not even once.
