I think MultiCX is nice enough... I haven't had any problems with the program...
As I saw in both VisualPrefs and Birdie documentation, the problems with MCP is quite many, but I must admit that I haven't tried MCP.
Actually I seem to recall that many docs mention MCP as a -be carefull with your doings, program.
But don't slaugther me on this, it's just how my intuition feels with MCP :-)
