Just thought I'd mention that the app known as wetter (a weather app) has been locking up my whole syste after 30 minutes. I found the issue, If you do not have access to the interrnet every so often it will beep and the ambient menu bar will turn red. If you ignore this for 30 minutes or so MOS locks up big time.

I figured it out becuase the system always went crap when the menu bar turned red and I knew who was doing that. Plugged in an ethernet cable and no more lockup. I was doing backups and saw no need for the net during the long process.

I have wetter setup to run on boot by the way.
