Modules:
Popups API 6.x-2.0-alpha5
WYSIWYG 6.x-1.1

I managed to get popups called everytime there is a node and a edit-node link. The popup displays the node-edit page and i can change the title or change attachements. If i do not use any extra editor i can change text in the body and i can save it. But of course I want to design the text. Make it bold or italic etc. I use the WYSIWYG-module (version 6.x-1.1) for that. But if a popup gets called and i make changes to the text the changes are not saved. If I create a new node and the WYSIWYG is activated the text gets saved.

I could not find anything similiar to that on drupal.org.

Is this a bug? Can you use popups and WYSIWYG to change text?

How does the content from WYSIWYG gets saved properly? If i display the normal body edit textarea with firebug (it disappears with display:none which is caused by the activation of the WYSIWYG module) and make changes to the text it gets saved properly.

I posted the issue also on the WYSIWYG module page since it is very hard for me to decide which module is messing up.
