morpheus locks up and crashes

[hatrack]

since upgrading to the new version of Morpheus 4.0.5, I have had a persistent problem of Morpheus locking up and crashing after about 1 hour or so of running. My operating system is windows xp. I have tried uninstalling and re-installing morpheus but no luck so far. Also when morpheus crashes it also locks up the whole system and I have to reboot to get out of it. Any ideas what the problem is

The newest version of Morpheus at this time is v1.85.
