newPing library clash

i am using HC sr04 distance sensor with the newPing library

the problem is

when i use new ping library , i am not able to use the tone functions

core.a(Tone.cpp.o): In function __vector_7': C:\Users\Harsh's\Desktop\arduino-1.0.3\hardware\arduino\cores\arduino/Tone.cpp:535: multiple definition of__vector_7' NewPing\NewPing.cpp.o:C:\Users\Harsh's\Desktop\arduino-1.0.3\libraries\NewPing/NewPing.cpp:214: first defined here

also when i use lcd.write(from the liquidcrystal library), i have to typecaste the value of a custom created byte .

any suggestions to how to solve this problem?

Use the old ping method then.

the old ping is not accurate

this newPing is pretty cool i would love it if there was a way to run the newPing library
