[SOLVED] Long press EditText crash: Unable to add window

I am trying to do a long click in an EditText, but when I do a long Click, I receive the error below. I would like to be able to do a long click to get the Copy/Paste/Select All context popup so that the user can paste text into the box.

Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@799bfc6 is not valid; is your activity running?

The EditText is in a ScrollView in a PopupWindow. So when the error occurs, I am currently active on an Activity with the PopupWindow open and I do a Long Click within the EditText that is contained on the PopupWindow.
