I have the following in a local logbook config: 
 
  append on edit = "\n\n[$date: $short_name]\n" 
 
When I upload an attachment to an entry, it appears like the page is 
getting refreshed in the browser and the 'append on edit' action is called 
again. This results in two appended strings in the text entry, one for the 
initial edit and one for the upload. 
 
Is this by design or an inadvertent result of uploading an attachment? 
 
My preferred handling of this - and perhaps a more intuitive behavior - 
would be to have the append/prepend actions happen once and only once for 
each edit or reply. 
 
BTW Stephan, many thanks for the great program.
