ABSTRACT:
A method for operating a computer system having a plurality of software modules which interact with each other by sending and receiving messages. The computer includes a user interface which receives commands from a user and displays information to the user in response to those commands. The computer system is characterized by a latency time defined to be the time between the issuance of a command by the user and the receipt of information specified in the command. The messages received by at least one of the modules include messages for that module and messages that are to be passed to other modules. In the present invention, at least one of the modules is provided with code for recognizing a Latency Event which includes a message for that module that would not normally be received by that module if the computer system had a latency time of zero. This code also contains code for storing information specifying that a Latency Event was received by that module.
