Script no longer works in mail V3 since upgrading from 10.4 to 10.5

Question

I used the script below to generate mail messages. Under 10.4 it would just send the message, now under 10.5 it puts it in the Out Box and that is it.
Anybody knows how to fix this so it sends it immediately?
Secondly I used to be able to set sender to any of my accounts for example "[email protected]" or any address I liked, this too is no longer working as it uses always the main account from Mail it is send from.
Anybody knows why or how to fix this?
set theBody to "abc"
set theSubject to "XYZ"
set theTarget to "[email protected]"
tell application "Mail"
set newMessage to make new outgoing message with
roperties {subject:theSubject, content:theBody}
tell newMessage
make new to recipient at end of to recipients with properties {address:theTarget}
set sender to "[email protected]"
end tell
send newMessage
end tell
thanks

I don't know if this is still an issue for you guys, but I've been experiencing a problem with the MouseWheelListener added to a Component that is added to an Applet. This is browser independent, but appletviewer/browser dependent.
Check this link for some test cases:

I thought it had something to do with the event getting "consumed" by other listeners, but it seems like it only has to do with the MouseWheelListener.
