hi Friends/Masters. i don't know if it is the correct section, i am sorry if i am wrong here...... My PC is running with Win 7 and now i have noticed when i am intending to open a linl with clicking on it ( from my E-mail for example), i am getting a window with "This operation has been cancelled due to restrictions in effect on this computer. PLease contact your system administrator". it was ok before one week. i am the only Person who has an account with this PC. what can be the prob,?? thanking you all in advance.......Chris.
