Several resources + the notification widget reload has changed in the latest nightlies. Crystal is based on the latest resources, so my suggestion is to move to the latest nightly.
I know that nightlies are tagged as highly experimental, but they really implement several new features and improvements that are worth.
Thanks for your help.
Well, I think t's time to move on, I guess I'll flash the latest nightly tonight, apply the theme, and send you some feedback
PS: Also I just wanted to know how to get the clock widget that @Dabbill has in the screenshot he posted. I would be great to have it.
