Version:           4.6 beta4 (using KDE 4.6.0) 
OS:                Linux

Use case: A friend sends me an email "Hey, I've moved. My new address is ..."
Currently there's no way (short of running kmail and kaddressbook separately) to keep the mail open and copy/paste the new address to the "Edit contact details" dialog.

Reproducible: Always

Steps to Reproduce:
1. Read email in kontact's kmail part
2. Switch from kmail part to kaddressbook part
3. Select contact to edit


Actual Results:  
The "Edit contact details" dialog goes modal, preventing me to copy the address from the email

Expected Results:  
I can switch from the kaddressbook part to the kmail part and copy the address from the email

To me, this seems like a very common use case, so I'd very much like to see it resolved.
