Locking up with patch 6 and/or the new Uterus map.  No lockups with patch 5 and/or the old Uterus map.  Obviously this new patch has brought out some kind of problem with my computer, since it can't be a problem with the patch.  All drivers are as current as I can make them (sound card driver is pretty old..... but it worked just dandy with Patch 5), Direct X 8.0a, Athlon 900Mhz,256mb Ram, Geforce 2MX.  All worked well before in patch 5 (although my computer was locking up before they released a different version of Baltic, once they released the new version the lockups stopped).
