Recently, Higher Logic, the company that hosts and maintains FieldComm Group's Workspace, made some changes to the user interface. Most notable are those surrounding documents.
In prior version, the document tree was displayed on the left side of the screen.
The new interface now has this located at the top.
Also please note that the document list does not show sub-folders, even through they may appear in the tree above. Please take care in selecting the correct sub-folder.
