View is blank when resizing or creating new one

Anonymous's picture
Forums: 

Hi, everyone.

While trying to excute sample programs, I found that the view is black-out when resizing child frame window or creating new one in NT.

The comments in sample source programs tell me that "Matrox" graphics cards might be suspicious and not well matched with opengl.dll graphic engine.

Pls inform me about this problem if anyone know the solution to avoid this.

Thank you. H.C. Kim
