Could someone please upload a copy of the file Opengl32.dll version 5.1.2600.21 that comes with Windows XP SP1a? Or version 5.1.2600.1106 that came with SP1?
I cannot find a version past 5.1.2600.0 that will let me download it.
Info on the .21 version: http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B312505
Info on the .1106 version: http://support.microsoft.com/default.aspx?scid=/servicedesks/fileversion/dllinfo.asp&fp=1
I am hoping that updating this file may stop some of the lockups I have just started getting in OpenGL games like Neverwinter Nights that started when I upgraded from a Nvidia Geforce 2 GTS to a ATI Radeon 9700 both with latest drivers.
