using both office 2003 and 2007

[rekt57]

i recently installed office 2007 enterprise edition on my computer (windows xp sp2). during the install i chose to leave the 'office 2003' install so i wouls still be able to use 'office 2003' if i needed to for compatibility reasons. i can open the two different versions separately without a problem, but 'office 2003' no longer shows up as a program i can use as a default for .doc, .xls, .pub, etc. even if i go through properties and find the 'office 2003' versions of word, excel, publisher, etc by browsing through 'program files\microsoft office\office11' to find the 'office 2003' version, windows still chooses the 'office 2007' version as the default.

i can run 'office 2003' and open the file i want from the that version and everything works fine, but i just can't figure out how to change the default program back to 'office 2003.' any ideas on how to do this?

thanks.
