I'm having a bugger of a time trying to update the version of Drush that's bundled with Acquia Dev Desktop (DAMP). The bundled version is 4.0-rc3 and lots of commands seem a bit wonky (e.g. pm-update) or aren't found at all.
I've tried 'self-update' and 'selfupdate' but they're not found. I've tried downloading Drush and overwriting the Drush folder in the acquia-drupal directory but the version of Drush doesn't seem to change when I run 'status'.
Anyone got any ideas/tips? I'd like to avoid moving away from using DAMP if poss as there are definite useful advantages and time-savers. Sadly, my Acquia forum post has received no response whatsoever :(
