A question was posted today on the forum regarding how to delete "saved filters"... I accidently deleted it when I was replying, so am reposting the question here.
The answer is...
Pull up the custom filter edit screen by choosing... "CREATE A CUSTOM FILTER...". From the window that pops up, choose the filter you want to delete from the drop down list in the upper left hand corder, then press the DELETE... button in the upper right hand corder and confirm your intention when asked.
