I know I can't delete the 5 that OE includes, but I created some, got in a muddle & want to delete them & start again.
Following OE Help, I clicked one in the folders list (am I right in thinking it means the list I get via View, Go to folder?) It says to then click File menu, point to the folder & click Delete. But when I have the folder list up, File etc. at the top are greyed out.
