Automatic close search window

hello, in order to increase the speed of our navision sql database we turned the find as you type funtion off. but now we have a little problem with the users who used this function… when you have activated this function and searched for a document no. the focus in the window was set to close, so that after finding the first record, the search window was closed… now there is the problem that the focus ist set to first and then to next, so that after finding the first record, the window will not close but search for the next record… can we set/change this behaviour in any property or option? thanks a lot
