don't have time to look into the various other AS issues/questions ATM
unfortunately but I do know how to fix this one, it is caused by
AppleScript 2.0 switching to unicode text (in Leopard IIRC), and
because tkMacOSXHLEvents.c is checking specifically if 'TEXT' (i.e.
text in the carbon system encoding, usually mac roman) was passed in,
the automatic coercion handlers between unicode text 'txtu' and system
encoding do not kick in. This is easy to fix, will try to get this
committed soon.

as far as a replacement for 'aete' is concerned, we will definitely
need a .sdef for TkAqua Cocoa to replicate the old functionality,
contributions by you or Philip much appreciated...

Cheers,

Daniel
