InfoPath Dev

I have Outlook and an the form open in Citrix right now.  The same link address works in the Outlook, but not in InfoPath.  So, I suppose the answer is yes Adobe is installed.

I have a infopath 2003 form that has a field that has for values a path directly to a pdf.  The the links work just fine, but when I use the form in a Citrix enironment it doesn't open up.  It does nothing, no errors or anything.  Why would a hyperlink not work in a form viewed in a Citrix environment?  Anyone?
