Comodo 6.0.264710.2708 SandboxIE 3.76 Also running EMET; Virt reg tweak on Comodo. Win7x64. What is odd is that when installing SB again, my icon in C: changed. I have a feeling SB is not installing properly because it only occurred now. Have you tried going the other way--installing SB then Comodo? Good luck.
