moving at different speeds

[Saz]

Hi Jeff,

many thanks for that; but when I try and load my .png file using this code, it fails to load it (similarly for .jpg files as well), also the markings on the texture I'm using need to move at a specific temporal frequency, which I've already worked out and my texture is moving on a continuous loop (agan which is already written). However when I try to assign one texture quad to one of the windows and one texture quad to another; they both end up in the left window
