Hi Aitor,

Sender is the originating object sending initiating the event. For
example, let us consider Button: TButton. The latter's OnClick event
can be used to call method:

ButtonOnClick(Sender: TObject);

Sender points at Button. So, inside the event handler, the cast
TButton(Sender) can be used to operate directly on the calling object.
However, Sender need not be used and it is normal practice in
Lazarus/Delphi code not to use it.

Regarding the following exeption, this is caused because
"/usr/lib/netman/bin/backend " was not found and the exception was
forwarded to the TApplication object.

TApplication.HandleException Executable not found:
"/usr/lib/netman/bin/backend "

I think, the error is simply an extra space at the end of:
backend=/usr/lib/netman/bin/backend

Edit the file /etc/netman.conf and see what happens. If you are not
using /etc/netman.conf, something else is causing the error, but I
doubt this is what is happening.

Also, as a test, try to remove the --auto-conn parameter and check
whether netman loads. If it loads, it would corroborate my conclusion
that the cause is an extra space at the end of the line mentioned
above.

Edward
