I'm presently on my son's laptop because I can't type in "certain" fields or
forms and email on my desktop. I thought it might be a setting in "Internet
Options" but when trying to view, I got message, "This operation has been
cancelled due to restrictions in effect on this computer...contact system
administrator.

This is a home PC running XP Home and IE 7.0

Please help me resolve this....I appreciate you help in advance !
