In 9.73 we notice that filter files are no longer found.
Example.
We have a filter based on the file
[MEfolder]\config\filters\patterns\MEFILTER-FROM.txt (since before v3 of ME)
but trying to edit it (via ME Filter Management -> Criteria Properties) we get message that
MEFILTER-MEFILTER-FROM.txt.TXT
is not present and if we create it next time we try to edit we get message that
MEFILTER-MEFILTER-MEFILTER-FROM.txt.TXT.TXT
is not present.
And so on...
So what MEFILTER is used if one?
P.S.
In your "Submit Suggestion or Defect Report" page you consider only improvements and so suggestions; but a defect require a solution not an improvement. So the "Severity" should be less optimistic.
