Problem while debugging rule

Hi All,

I am faciing a problme while trying to debug rule from standard tcose-PFAC.

In below rule one of the value OBJECT below is defined as below.

When i entred all the values in above rule and then entred BO value, all other fields dissappear.

Also if i scroll down on rule window, the values in individual field gets cleared some times window disappears.

Can anybody guide me how to handle this and how to debug?

Thanks,

SD
