Multiple Internet Explorer Instances Do Not Redraw Screen Correctly

• Microsoft Internet Explorer versions 3.02, 4.01 Service Pack 2 for Windows NT 4.0

SYMPTOMS

When you start multiple new instances of Internet Explorer (for example, by pressing CTRL+N) and then move the windows around the screen, the browser's window data may be corrupted. This occurs only on multiple-processor computers with the color palette set to 256 colors.

CAUSE

This behavior is caused by the way Mshtml responds to the WM_PAINT message.

RESOLUTION

To resolve this issue, upgrade to Internet Explorer 5.01.

WORKAROUND

To work around this behavior, use any of the following methods:

• Set the color palette to more than 256 colors:



1. Right-click the desktop, and then click Properties.



2. Click the Settings tab.



3. In the Color Palette box, click a setting with more than 256 colors.



4. Click OK.



• Disable all but the first processor by adding "Numproc=1" to the Boot.ini file.

STATUS
