No response when task options are selected

Hello there,

I am a new member of the Forum and need help from anyone with knowledge of Comodo Firewall v8.00.4344 for Windows XP sp3.

I have been using Comodo for a long time now with no problems and recently upgraded to the above version.

When any Task then any Option is selected, the option is highlighted but nothing else happens. I am at a loss as to what is happening.

I would really appreciate anyone’s help.
