NIS 2012 19.2.0.10: problem with Smart Firewall Program Control

 

I have the following problem (Win 7):

 

when I try to activate the pull down menu in the Smart Firewall/program Controll setting, or to add ar program to firewall rules, NIS crashes and I get message Symantec service framework stopped working.

 

No problem if I use the Modify option to change firewall rules of one already listed program.  Crash happens only with pull down menu or adding a new program.

 

If I restart the computer and run Get Support, Norton Autofix  tells me that item has been fixed, but then  I still have same problem.

 

Any help?

If not, I'll try to run NRT and in case reinstall NIS?

Thanks.
