Does NVIDIA card support "WGL_ARB_make_current_read"

My FX5200 card’s OGL extenstion string shows it support “WGL_ARB_make_current_read”,but the “wglSetContextCurrentARB()” always return FALSE.Many threads in the forum says NVIDIA card don’t support the extenstion,is it true?

It’s “wglMakeContextCurrentARB”

Yes,the function’name is “wglMakeContextCurrentARB()”,I forgot the spell of it in my previous thread,but it always return FALSE in NVIDIA Geforce FX5200,why?
