i also have a similar problem..
i have created a custom button onclick of which i open a PopUp DIV ...
on that PopUp Div i have a button.
onclick of that button i call the pasteHTML function .. and the popup div is closed.
on mozilla and chrome the html gets paste where the cursor position was...
but in IE it gets pasted at the start of the editor.
why is it so?
is there a solution for IE?
