Hi Mark, Problems where one machine reproduces the problems while others don't when using the same models and code base tend to suggest either a threading issue, an unitinitailized variable or a buggy OpenGL driver.
Run osgviewer single threaded via: osgviewer --SingleThreaded flight1_0.flt I doubt this will effect things, but its would at least tick one possibility off the list. Robert.
