I think as long as an AE handler is registered, AE's are received, I 
suspect this might be plugged in on top of carbon events? e.g. AlphaX 
doesn't see AE's destined for tclAE in its WNE event loop. OTOH 
clearly neither tclsh nor tclAE is calling RAEL

I've actually noticed the other day that tclAE doesn't load if you're 
logged in remotely and not root (with the usual port permission 
errors you get when trying to connect to the window server from an 
unauthorized source):

kCGErrorIllegalArgument : initCGDisplayState: cannot map display interlocks.
kCGErrorIllegalArgument : CGSNewConnection cannot get connection port
kCGErrorIllegalArgument : CGSNewConnection cannot get connection port
kCGErrorInvalidConnection : CGSGetEventPort: Invalid connection

so some kind of registration with the window server seems to take 
place when we load TclAE and thus Carbon (as we obviously need 
AE.framework ...)

when root, tclAE will load but e.g. the finder still doesn't accept 
AE's from  you...

Cheers,

Daniel
