Just a quick question - Ive just written a small program to draw a coloured triangle and a quad on the screen (using NeHe's tutorial 2 or 3 as a basis, and NOT USING C++) Whenever I either resize or minimize the app the two shapes disappear and dont return. Any idea what could cause it?

After snooping round MSDN Im assuming it has something to do with the WM_SIZE message in which only my resize function is called so Im assuming the problem is in my resize function:


' Set the viewport
glViewport(INT(0), INT(0), INT(Width), INT(Height))

glMatrixMode(GL_PROJECTION)
glLoadIdentity()

' Setup ortho projection
glOrtho(-0.5, (Width - 0.5), (Height - 0.5), -0.5, -1.0, 1.0)

glMatrixMode(GL_MODELVIEW)
glLoadIdentity()

RETURN
