error on changing project options??

hi,

i want to convert or update my components to bcb6, but if i want to edit the
project options in text mode, it seems that nothing has changed! so i have
closed my package and opened it again! and really nothing has changed! the
libs i have deleted are always there! if i edit it with my ultraedit and
save the file i get the message 'no project rules found'. whats going on?

thx to all
bernd mayer
