Hi everyone!
Basecamp has problem with import into library!
1. Select root directory 'My collection' in the library
2. Then press File ---> New ---> List Folder
3. Select new created list folder
4. Press File ---> Import into 'New Folder'
5. Select any file, for example, *.gpx, *.gdb etc. and import it
6. This selected file is imported into root directory 'My Collection', but not into desired 'New Folder'. The 'New Folder' is empty!!!
So you have to press "Move To..." in the context menu of new imported file and move it into correct 'New Folder'. :(
Please, fix this bug!
