URLs from ISI Web of Knowledge exported as hyperlinks

Dear forum members,

I guess this is a common problem, but I couldn’t find any related previous forum threads:

URLs to Web of Knowledge are displayed in EndNote as something like “<Go to ISI>://BIOSIS:PREV200400379583”.

Within EndNote, these links are clickable and lead to the correct record in WoK. But when exported into other formats (e.g. HTML), the links are, of course, not working any more. How can I transform them so that they become valid hyperlinks (“http://…”)?
