Hi Vin.. I’ve tried 4 flavours of MC: 3.0.0, 3.0.5, 3.1.1, 3.1.2. The xw4300:3.4GHz hyperthreading Pentium, 1GB RAM, Windows XP SP2. As I said initially, it was working fine until an install of other software and, if my memory serves me correctly, an automatic update happened by mistake. I have removed all the Windows updates from that day, but no difference. Stu
