Subject: [openbox] Execute Action Not Forked (Wrong PPID)
Message-ID: <20190807051229.GA27982@midnight>

Hello.  Here are steps to reproduce something that I really don't  
understand:

• Put obForkTest in your home directory.
• Put the two lines in the attached rc.xml into the <keyboard> section  
of your real rc.xml.
• Restart Openbox and try out the two keyboard shortcuts.

For me, the W-o shortcut results in a chromium window that stays open until  
I close it.  The S-W-o shortcut, however, results in a chromium window that  
closes after 10 seconds.  The attached process trees provide a hint: For  
the W-o shortcut, chromium is correctly backgrounded and given a PPID of 1.   
On the other hand, for the S-W-o shortcut, the xterm instance is assigned  
a PPID of openbox (1116), and chromium is never backgrounded at all.

Why?

This is a problem because I have created a similar hotkey command, but  
its spawned programs are immediately killed!

(For testing purposes, feel free to substitute appropriate programs for  
xterm and chromium.  I certainly did.)

Thank you.
