SUMMARY
An OpenGL application must select and realize its palette before setting the current rendering context with wglMakeCurrent.

MORE INFORMATION
An OpenGL application typically makes its rendering context current one time only when the application is created, or repeatedly just prior to rendering, as in WM_PAINT for example.

In the first case, the palette must be created, selected, and realized prior to the initial wglMakeCurrent.

In the second case, the palette should be selected and realized before every call to wglMakeCurrent.
