Can't Focus in Dialog within GWT Dialog

Hello. I'm attempting to use CKEditor within GWT using the gwt-ckeditor wrapper. My use case requires that the editor be within a GWT dialog box. I've gotten CKEditor to show up fine inside this dialog, and I can type text and make all the standard basic markup. The problem is when I try to add a link or image or use any CKEditor feature that opens another dialog on top of the basic CKEditor textarea. The additional dialog shows up, and z-index values appear to be correct enough where the dialog appears on top....but I cannot click or type anywhere in this dialog. I can't even click on the X or Cancel buttons to close the dialog. If I can't solve this issue, I won't be able to use CKEditor at all in our product. Any ideas?
