Comment 1 for bug 604931

Okay, do this ...

Press <F9> and go to the menu. Toggle off, and then back on the "launch by default" option. It should be the last in the menu. This will re-write the last line of your ~/.profile with the latest incantation.

Look in your ~/.profile. Do you see a line that looks like this?
  case "$-" in *i*) byobu-launcher && exit 0; esac;

Edit ~/.profile and change that line to say:
  case "$-" in *i*) byobu-launcher; esac;

ie, drop the "&& exit 0" part.

Now try your use case again. Does it now do what you want?

If so, let me know. I can try to add a configuration option to make this behavior toggle-able too.
