How to force the paste as plain text?

config.pasteAsPlainText = true;

Hmm... I tried it a long time ago and it worked for me (I don't use it anymore) - maybe something is broken now...

You can use my answer to your other mail: http://cksource.com/forums/viewtopic.php?f=11&t=23621 - and just ignore all tags - only accepting text...

Helmø already told you how.
There's no mystery about it
