Afpd locks up on laptop
 

Just got afpd on the 24th ,got to say pretty awesome sim.I have an Insprion 8500 dell with 512 of ram good graphics.Afp old version runs perfect on it and so did afpd initially.After 20min or so it locks up for no reason at all.I have also a amd 2200(main pc) with 512 ram 128 nvida etc.The program runs flawlessly on it,at about 120 fps.On the laptop it runs at around 90 fps.The only way to quit "afpd"is to shutdown with the power button no other method works. Any ideas?
