Ethernet + Virtual Wire Issues

Hi All,
the problem is that ... looking Servo.cpp: (line 103) and VirtualWire.cpp (line 416) that function SIGNAL (TIMER1_COMPA_vect) is present in both ...

Then I've change the function in VirtualWire.cpp putting SIGNAL (TIMER6_COMPA_vect) because the other one arrive until 5 ... in compile mode there is no problem ... but I've note that the serial monitor is not working anymore ...due the fact putting back like initial the serial monitor can works ...

How I can do to remove the issues and continue to work ?? SIGNAL (TIMER1_COMPA_vect) maybe is call in other parte that I didn't know ... I can try to modify to the servo.cpp part ?

Thanks for the support,
Andrea
