ar invoice document total did not automatically pop out

Hi,

my client has been using accpac for a long time. Now her accpac version is v2019.

she claims that after entering ar invoice detail lines, there will be a popup to display the detail lines total, so that she does not need to go to totals tab.

she says she does not know what she did and now this function is gone. FYI, there is no customization of her accpac screens.

im not sure if this is one of the tips/tricks, kindly please advise.
