Roger, This isn't so much a PyMOL bug as a flaky characteristic of OpenGL under Windows XP, which eventually stops updating the screen when an application like PyMOL attempts to draw continuously for a long period of time without relinquishing control back to the operating system event loop.
PyMOL isn't actually frozen when this happens -- it continues to render and write out images. Windows simply isn't updating the screen. The problem doesn't exist on Windows 2k or Linux, but a very similar behavior occurs with MacPYMOL (but which can be worked around by dragging the MacPyMOL window). Eventually we'll rearchitect PyMOL's event loop so as to eliminate this annoyance.
