I can confirm this is a wider-scale issue as it doesn't work for me.
Mozilla Firefox 20.0.0.1
I'd fix it, but I don't have template access 8-|
Gheis or Cannon will likely need to stab at this, with all the pain that involves - if the community thinks it's important enough.
This seems to be an issue with the Dark Ice theme itself, as far as I can see on my unmodified MyBB installation - the "Check all" button works fine on any other theme, just not the Dark Ice one. I personally didn't find anything obviously terribly wrong by looking at general.js or the differences between HTML code for the PM inbox page on each of the themes, so I'm not sure what the issue actually is.
I'd suggest reporting it to Audentio Design and letting them deal with it instead. It's probably more bother than it's worth to fix this minor issue which has gone unnoticed for half a year when you can get someone else to fix it for you.
