  • Microsoft Windows XP Service Pack 2, when used with:
    • Microsoft Windows XP Professional
    • Microsoft Windows XP Home Edition


On a computer that is running Microsoft Windows XP Service Pack 2 (SP2), you may receive a Stop error message when an application draws the bitmap by using the mask. The Stop error message resembles the following:

0x50 {e4939000, 0, bf971fe6, 1}

Note The Stop error message may occur in the following processes:

  • win32k!prunPlgRead32
  • win32k!prunPlgRead24
  • win32k!prunPlgRead16
  • win32k!prunPlgRead8


This problem occurs because some functions in Windows XP SP2 access invalid locations that exceed the mask bitmap buffer. The buffer is exceeded because the pointer is increased more than is required.
