Problems with GL_ARB_multisample and WGL_ARB_buffer_region in combination DriverBug?


I have a Problem

I want to use the extension WGL_ARB_buffer_region

it works fine but if I activate Multisampling with GL_ARB_multisample extension the Program hangs up
by the “wglSaveBufferRegionARB” command.
I must the restart the PC because it hangs up the hole PC.

if I initialise the Program without Multisampling it works ok.

is this a Driver Bug or why these two extensions do not work together?

I have win2k, Nvidia GForce4, driver 29.42

thx wedge
