in reply to File::Tail behaves funny

I was unable to reproduce your problem using AS/5.8 and File::Tail 0.98. How are you appending the lines to the file fox.txt?

Total speculation: Is it possible that your using an editor that is buffering the output and only updating the file every 10 seconds or so? Are you explicitly re-saving the file after the additions, or are you just adding to the file already opened in the editor and allowing the autosave feature to do the saving?

Examine what is said, not who speaks.
1) When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2) The only way of discovering the limits of the possible is to venture a little way past them into the impossible
3) Any sufficiently advanced technology is indistinguishable from magic.
