I also believe DCEW is the culprit.

I had DCEW and five widgets on the desktop, showing uptime, some IP addresses, and two buttons that turned bluetooth on and off.

With that setup, I started noticing the bluetooth DCEW widgets freezing up. Was having to reboot twice daily.

Assumed I had a bad script somewhere. Deleted the .desktop_cmd_exec file. All five widgets reverted to the "uptime script". Ran that way for a day. Still had to reboot often.

Finally uninstalled DCEW. Haven't rebooted in two days.

Hope this gets fixed, because I love DCEW. Enjoy using a script to do a simple function rather than downloading a separate app for each one. Feels more linux-ey.
