How to change Request Read Receipt default action

[Doctor-Who]

I'm looking for a way to change the default action for the request a read receipt dialog box from "ok" to "cancel".

I found it once before, but it was so long ago I forgot where I found it.. :ermm:

Any assistance would be appreciated..

Thanks...

Have a look in my profile. You will find a hack that is not 100% what you ask for, but i think you might find it even more usefull.

It's close but it's not exactly what I'm hoping for.. I still want the "request a read receipt" to pop-up when sending a new PM, I just want the "cancel" to be the default action so people just don't hit the return key and request a receipt by accident - I've done that myself by accident..
