put pure-data-svn/scripts/guiplugins/dropsuite-plugin/ folder into your pd-external folder, restart pd if it doesn't complain about missing something that's all.
yep, it's complaining a lot, since i am not on pd-extended anymore but on vanilla (also due to heavy recommendations on this list) ;-)
anyway: thanks a lot for all your efforts !
i built a dirty little workaround on my system (windows 7) with AutoIT (the gaffertape for those who can not code) and everything works fine now ! (in case, anybody is interested, my script is attached)
thanks for all help, saved me a lot of clicking and typing !
cheers
