IIRC easrly CFP releases prevented the use to rearrange Computer Security Policy applications.
This limitation was then removed when Comodo approved user feedback requesting that.
After rule sort limitation was removed I believed that the rationale behind that was superseded but it looks like I was wrong to assume that All Application policy was applied first regardless its position.
As there is no official description about the design behaviour I guess no one really is able to undertand this.
EDIT: striked out incorrect assertions
Can you please describe the design behaviour?
Does that overriding behaviour happens only for Execute access rights?
