Don’t know the answer to your problem but I don’t use hyperlinks and
if you cannot find a solution to it you can try this

I don’t use the hyperlink I only store the path in my database

Ie

C:\programfiles\mydocuments\document.doc

Or

http://www.google.co.nz

I then assign this to a control and use onclick to run this code

Application.FollowHyperlink mycontrol.Value

Hope this helps
