Question about Excel Add-in used in Citrix

[kmfloyd]

Does anyone know what would cause a library not to display when trying to access while in Citrix?  If you log onto the server and access from there, you see the library just fine.  This seems to have come up out of the blue.

You dont see the whole library or just it's content? Is this a question of some specific library while others are working fine?
Is the path to library in a right format? I mean, does it use network path like \\server\library instead of local path like C:\library?
Are the FileSys.ini file and the rest of the content in UNC folder accessible from citrix environment?
