FrontPage 2000 and PhotoDraw 2000 on machine with Office 2003?

I recently got a new computer (Dell Optiplex 745) and upgraded from Office 2000 Pro to Office 2003 Pro (running on XP Pro). I still have to use FrontPage 2000 and PhotoDraw 2000 for maintaining a website I inherited, so I loaded them in addition to the 2003 Office suite. Is this a problem? Does this confuse the Microsoft auto updating process or cause other issues that I may not be aware of? My Outlook address book went missing, so I don’t know if that’s related (I posted a question about that at https://www.techrepublic.com.com/5208-6230-0.html?forumID=101&threadID=212809&messageID=2287136&tag=nl.rCOMBINED)

I plan to uninstall FP and PhotoDraw after I redesign the website, but in the meantime would like to avoid problems. Thanks for any help.
