Well, i don't know (if the way Apple has implemented it) whether "off" means completely out of the picture... or if "off" means 1 Space. I just downloaded CornerClick and see some mention of Spaces in the ReadMe:

What's new?

version 0.8.2:

Bug fix:

Fixed the "An old version of CornerClick was active (version 0.0)" bug

version 0.8.1:

Leopard Spaces

Added compatibility with Leopard Spaces, so that the CornerClick actions function in all spaces.

[Version 0.8.1 will work only with Mac OS X 10.5 Leopard]

And it seems to contain a background app inside the prefPane.

Just saying that it wouldn't be out the realm of possibility that 'CC' itself could be part of this issue. [faceless background apps can sometimes not play properly with Finder, by stealing focus even when it looks like Finder is frontmost.]
