Has anyone else had spoilers freeze shut without flying in clouds, were
it seems like you should be expecting it to happen?

I had the ailerons and I think the elevator freeze up on a wave flight
in a Std Jantar many years ago. I broke the controls loose with
increased stick forces and made sure I kept the stick moving a bit
after that. Didn't enter cloud so assume moisture in the control
circuits or control hinges froze.
