Excel 2007 hyperlinks open with wrong program
 

I use Excel 2007 and have item numbers hyperlinked to product photos (.jpg's
are located in My Documents). For years I have had them open with Vueprint
and now all of a sudden they are opening with Internet Explorer. The file
association is still Vueprint. How can I change this so they open with
Vueprint again?

Thanks,
Russ
