I've noticed the Gmail widget won't refresh, but I have the same issue on my tab.

Everything else seems fine (that being said, the only non HTC Widget I have installed is Shazzam). I'll stick some more on and monitor tonight though.

 

Same problem here. I can't get a third party clock or battery widget to work. HTC support is useless as well -- they suggest clearing the app data, soft resetting the device and failing both, hard resetting.

 

I think the problem has something to do with the HTC Fast boot option in the power settings. I unchecked the option yesterday and my widgets haven't stopped now for almost 24 hours.

 

I was having problems with weather/news widgets not updating so i tried apex launcher and all the widgets now work fine so it has to be a sense issue.
