other thing i found

if i want to delete this rule i must unchick it and press ok then go back and delete it!!

 

i tried RC and same problem, if i made rule for program and delete the source and tried to delete the rule error message apears, i must unchick them first then press ok then back to delete unckicked rules

 

Did you create the rule manually or in interactive mode? I coulnd't reproduce it with manually created rules.

 

yes, i tried it with team viewer portable, when i delete it and try to delete the rule, i couldn't

 

i tried it again, and i created it in interactive mode and didn't delete the source file and tried ti delete the rule same problem
