I don't know what you mean by preview not working. When you hit "Save" 
you should definitely get a big version of what ever you seen in the 
preview window. It's possible that you can change a snapshot setting 
after getting a preview (refresh) and before saving it, which should 
have invalidated the Save button but didn't. Those are nearly trivial 
problems and easily worked around. (Hit "refresh"). Or maybe you expect 
File->Snapshot To Disk to do the same thing as the Save button. (It

These are all Windlight bugs. The problem with particles, clouds, etc. 
not honoring Freeze Frame is one of my biggest annoyances too, BTW, but 
from a pure user's perspective, it's valid to call them Snapshot bugs.

Yes, I'm aware of the meta task, but notice that about half of the 
issues are already closed. I expect many more are invalid. I'm not 
saying there aren't problems with this or any other major feature. I 
just wouldn't suggest that it's "broken" or otherwise unusable.

> I have the bad feeling that no one is working on snapshots anymore. Someone did till 1.23 and broke something with each subrelease, I saw no improvement, only more bugs.

That would me me who made most of the recent changes to Snapshots 
through 1.23 when I left the Lab. Perhaps you don't consider the ability 
to save in JPG and PNG formats to be an improvement but I and a lot of 
other people feel that was huge. I'm also particularly proud about 
clarifying the top "Snapshot destination" choices, adding the "Save As" 
drop-down option as well as a ton of code clean-up under the hood. I 
also removed a stupid 1 second delay between when you hit Refresh or 
File->Snapshot To Disk which action photographers should love. Another 
developer added a lot of new support for cropping and other controls 
regarding aspect ratios.

It's certainly possible that in the process of doing all the above and 
more that I broke some things, and for all of those, I apologize. It 
certainly wasn't for lack of care, effort, or testing. So while one set 
of bugs might have been replaced by some others, you certainly can't say 
that there's been no improvement.
