Desklet and extension list are working randomely at 0.23 east time
I meant to mention this myself... same thing here: Desklet and Extension managers refreshe their respective caches as they should. I did not have random (i.e. intermittant) behavior with them. Seemed to work as they should.
I really think there is a server problem.
I examined my Spices.py file (/usr/lib/cinnamon-settings/bin/Spices.py) and did not see anything glaringly wrong (although I'm still learning the Linux system). The fact that the Applet Mgr DID work well on my system several days ago again suggests a blinky file server somewhere. Let's wait until the work week starts back up... Don't re-install your system yet!
Calif dreamin' tonight... 75F and balmy... (strange for even here)
