Yo....So i'm still trying to get this hot key thing to work and i've gotten a little farther...maybe. I found the right API calls to hook a windows messages. I'm getting all sorts of messages about a Win32::GUI window I created, keystrokes etc. The problem is the hotkey message still isn't coming through. So i think there is a problem specificaly with either the hWnd returnd by Win32::GUI or the constants I've used, or my understanding of the problem at all. So if any Win32 gurus could lend me an eyeball and maybe a few brain cells i'd appreciate it.
