this viewer is much less memory intensive, is singled-threaded, and does not rely on Gtk 'input_add' (which often causes deadlocks, memory leaks, etc.), Also, unlike the Ayttm cam viewer, this viewer is an EXTERNAL program (meaning that IF it does crash, it will crash ALONE instead of taking down Gyach Enhanced and your Yahoo connection with it - I think 'risky' apps are best run separately)...als
