People picker issue in Modal dialog box

We have a page with People picker ( <SharePoint:PeopleEditor> ) control added to it.

This page is opened as a Modal dialog box using SP.UI.ModalDialog.showModalDialog() from another page.



We have following issues in People picker only when we open the page as dialog box. Works fine if the page is opened as normal page



Issues:



1. Cannot remove the resolved name from the people picker control

2. When 'Remove' menu is clicked for an invalid user name, the input box goes invisible.

Issue is only in IE. Working fine in Firefox and Chrome. Using IE10
