title: mcedit and mcview - subshell not work on Ubuntu Linux, on mc - works well
body: <p>I have the problem with not working subshell on mcedit and mcview of Midnight Commander package on all my Ubuntu systems.</p>
  
  <p>When I in mc file manager, ctrl+o drops me to the full-featured shell (bash), so I can see previous shell output, type and execute commands.</p>
  
  <p>But when I on mcedit or mcview application, ctrl+o only shows me previous shell output. So I see black sceen with provious output but without cursor.</p>
  
  <p>And when I try to type anything on this screen, I goes back to mcview or mcedit.</p>
  
  <p>Problem is reproducible on normal user, on sudo and on root user too.</p>
  
  <p>mcedit and other apps compiled "With subshell support as default", here is output</p>
  
  <pre><code>$ mcedit -V
