Probably a context problem
I have wrote an application that uses selection mode ( glRenderMode(GL_SELECTION) ). It draws some objects, and user is able to point some of them by clicking them. Everything is ok, when I run it on my PC (Win XP + Radeon 9100), it also works fine on Win XP or Win2k + GeForceMX440. ButÖ at school, on Win98 or XP (I donít know graphic card) it fails to render correctly. Itís ok until user clicks to select sth, then graphics stops refreshing, wglMakeCurrent returns false. Problem is, I canít write code and test it there, only at home, where it is running correctly, but I need it to work there. I would be very thankful for any suggestions.
