SYMPTOMS
When running Visual Basic on a system using Windows NT 4.0 Service Pack 3 or 4 with the video mode set to the True Color display, a compressed 32x32 version of the icon appears in the Title bar of the form despite the fact that the icon file contains a 16x16 version of the icon. Assuming that the icon file contains both a 32x32 and 16x16 version of the icon, Visual Basic should display the 16x16 version.
STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
This bug was corrected in Visual Studio 6.0 Service Pack 3.
For more information about Visual Studio service packs, please see the following articles in the Microsoft Knowledge Base:

MORE INFORMATION
This section illustrates how to create a sample project that demonstrates the bug behavior. It assumes that you are running Visual Basic on a system using Windows NT 4.0 with Service Pack 3 or 4. The display setting of this system must be set to True Color. The section also assumes you have an icon file with a 32x32 version and a 16x16 version of the icon.
Steps to Reproduce Behavior
- Start a new Visual Basic Standard EXE project. Form1 is created by default.
- Set the Icon property of Form1 to the icon file.
A compressed version of the 32x32 icon appears in the Title bar of Form1. The expected behavior is the 16x16 version of the icon appears in the Title bar.
