Good news. I have finally found "the bug" which was responsible about the duplicate notifications for the same program. Now, when a rule is created, WFC will no more nag you again with the same notification. Finally. I'm still doing some more tests and in a few days I'll publish the new version. Thank you all, for your patience and support. Even it is a small 250KB program, it has thousands of lines of code which I have to check and debug. Pretty hard task, I never thought it will be so difficult.
