To reproduce:

• open ccl Windows IDE
• close the listener
• notice in the console the error "document: selector not recognized"

I don't know if I built something wrong, because I don't remember this before, but maybe I just hadn't tried before: resizing behavior is broken in some bizarre way. E.g. clicking on a window border causes the window to jump to a different size, can't make it any smaller by dragging.

Hi,

The compiler seems to use algorithms for type derivation that are worse than exponential with the size of forms compiled. I see this on both IA32 and X86-64 ports, running Linux.
