ABSTRACT:
An information display apparatus having a multiwindow system designed to achieve high speed image drawing without impairing the operability of the multiwindows. In this apparatus, a communication controller sets an exclusive mode discrimination flag when a request to do so is generated by an application program. The displaying capability for all other application programs is then suspended. If another application program then generates a request with respect to window management, the communication controller checks an application program management table. When the result of the check indicates that the request is generated by a suspended application program, the request is stored in a communication buffer and processing of the request is suspended unless the suspension of the processing is cancelled.
