i had this experience earlier in which i need to close the app for the db grid to update even

i have these components:

1 zconnection
1 ztable
1 datasource
1 dbgrid
1 navigation bar

if i press refresh on the nav bar, the entry on the other computer wont appear. i would like the dbgrid to update when i click the refresh button whenever someone edit it's contents.

i also think that the database might "overlap" the entries from 2 or more users.

some users say i need to call commit, how do i do that and do i need to put it on every db grid i have on the application?

btw i am using delphi 7 and zeoslib 7.0.3

thanks
