Often when I issue a bash command, the results opens in a popup buffer, instead of going into the RESULTS drawer. F.ex this command.

#+begin_src shell nc -w 2 -v -z danzinger 8507 #+end_src 

It opens in a popup buffer

Connection to danzinger () 8507 port [tcp/*] succeeded! 

If I instead issue a "date" command, the results goes into RESULTS;)

Any pointers?;)
