By default, Visual Assist writes parsing messages in the status bar of the IDE. Depending on your IDE and your installed plug-ins and extensions, Visual Assist might overwrite important content, e.g. compiler warnings during step-through of Visual C++ 6.0.
Hide the messages from Visual Assist by editing the registry.
Visual Studio 2002 and newer
HKCU\Software\Whole Tomato\Visual Assist X\<IDE spec>\EnableStatusBarMessages = 00
Visual C++ 6.0
HKCU\Software\Whole Tomato\Visual Assist X\VA6\EnableStatusBarMessages = 00
Set the registry data to 01 for default behavior.
