I'm doing some research about our company's portal. We host a few apps there, most from third parties (timekeeping, for example). We had someone develop an app a few years ago that consists of a main map of links (hotspots on an image). The links lead to sub-pages that dynamically link documents from a directory. The problem is that, while the front page of the app loads and works fine, clicking any of the links removes the portal tabs and heading.

I've noticed that the other apps we have maintain the same visible url (i.e. www.blah.com/ApplicationName.aspx) even when you click a link. For this app, the address starts out that way, but clicking a link changes it to www.blah.com/subdirectory/ApplicationName.aspx.

Any help would be appreciated. :)
