I figured this out after a lot of googling. This happens when a background process in Mac OS generates events that inadvertently grab the window focus. See this discussion, esp comment #48, which includes a script to help diagnose the problem:
http://xquartz.macosforge.org/trac/ticket/58 The same HP software on my machine was doing this. The fix is to permanently disable the service (it seems unnecessary) by running the following. launchctl unload /Library/LaunchAgents/com.hp.help.tocgenerator.plist sudo rm -f /Library/LaunchAgents/com.hp.help.tocgenerator.plist For more details, see: https://discussions.apple.com/thread/2788162 Hope this message at least helps someone else who might have experienced the same issue. x2goclient now works perfectly for me on Mac.
