Why do Dfs links on a Dfs share appear greyed out when I try to open them from within certain applications?

This is a refresh issue that is a known limitation with certain applications that were written using Apple's Carbon API, but not applications written using Apple's Cocoa API. The work around is to change the folder view in the "Open" dialogue window of the Application or to cancel out of the "File - Open" dialogue in the affected application and then go right back in and try to open the share again. The second time you attempt this, the links will not appear greyed out.
