Paintbrush May Not Save Pasted 256-Color Images Correctly

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

SYMPTOMS

If you paste a 256-color image, such as a scanned image, into Windows NT Paintbrush from the Clipboard, Paintbrush may not save the image correctly to disk.

The image appears correctly in Paintbrush, but when you save the image and reopen it, it may appear as if it were translated into a 16-color image or it may appear solid black.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.1 and Windows NT Advanced Server version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
