List Dialog Box in Spotfire Not Working on Remote Machine

Has anyone had an issue where their "List" feature didn't work in Spotfire? View -> Lists 

Example, I created a List based on some marking in my .dxp and when I click on that List it marks that data (similar to how it works with bookmarks I guess,)

But that same exact action is not working for someone that is working through a remote machine. Through his remote machine, he can't even right click on the List dialog box or do anything at all except for close the List. It works on his local machine fine, but will not work on the remote machine. The List feature is the only one doing this - his other Spotfire functionality works fine.

It is the same .dxp file too that is saved in a shared drive.

Any thoughts?
