Protected Text Deleteable

I have protected my text, but if i move my mouse to the column of a row (i can see the Cursor of the mouse is cahnging into do Arrow Down - i think it should select the whole column) i can select the column and hit the Delete KEy which deletes the protected text.

I am using

ProtectedProp               := [ppAllExceptForEditFields];
    EditOptionsEx               := [wpTABMovesToNextEditField, wpRepaintOnFieldMove];

A second problem is that the user can move textboxes - and resize them - what shouldn't if the document is protected!
