i just noticed this bug in explorer interface: when right-click on a file or folder => Download...
(1) it downloaded to "my documents" and (2) without asking where i want it saved.
i was logued in with a login profile/session with set Local and remote directories in Session settings => Environment -> Directories
In explorer mode, it started fine in remote dir but not local dir. (this may be why. please to check if "local dir" variable is properly init. with user settings)
In commander mode, it started properly in remote/local dirs.
