There is (was?) a check for debug-launch in erlang launch config delegate, so this is strange... No interpreting should be done on "Run", although the user might want to add interpreted modules in the "interpreted module" view.
(The Run/Debug distinction doesn't map well onto erlang.)

When running without debug, the user shouldn't open the debug perspective! :-)

The run/debug distinction is still important, as running interpreted code is so much slower.

This works now as expected. Was probably solved a long time ago...
