Borland Object Windowing Library-Based Programs Slow System

Last reviewed: May 6, 1997
Article ID: Q101093

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1

SYMPTOM

Your screen saver may pause or freeze. Other applications may run slowly. Performance Monitor will show CPU usage at 100%, even if the Object Windowing Library-based application is running in the background, idle.

CAUSE

Applications developed using Borland's Object Windowing Libraries slow down Windows NT because of the way they handle idle time. Their message loops are such that if no messages are available they execute IdleAction() which soaks up CPU cycles. The intention under Windows 3.1 was to provide a way to do things in the background.

RESOLUTION

There is no resolution at this time. Please contact Borland technical support for more information.
