Hi, I'm new to this. Just got my Dell Inspiron 1545 on Dec. 3rd from dell.com.. Love It but I'm trying to find out how to Encrypt a folder that I put onto my Desktop home page.. I read up and went to right click, props & advance & click the 4th box which says encrypt content to secure data but the box will not allow me to check mark it, it's dim.. I have two current boxes checked and 1 Unchecked.. I've checked & unchecked them and the dim-lighted box still wont allow me to check it? any help here please? Thanks all inputs is really appreciated..
