Re: OS X :drop-callback on layouts not getting called

So, looking closer at the documentation and class browser, it would 
appear as though the drop-callback isn't actually supported for 
column-layouts. However, I'm still surprised that it works on Windows. 
I'm not at a Windows machine currently, but is the class hierarchy for 
CAPI different on Windows and OS X?

Anyway, having drop-callback support for layouts that aren't 
pinboard-layouts would be *extremely* helpful.

But, if I'm just missing something obvious, I'd be quite happy to be 
corrected. ;-)
