Java3d in dual monitor

I m facing a strange problem ,actually we are visualizing a 3d cube on a canvas3d ,it runs properly on one monitor but when we use dual monitor and open it in the second monitor it hangs.

i think it is the problem with java 3D api.because the exception occurs in java3d native code.can u suggest me any solution.and plese tell me also that which java3d Api version is latest that u guys are using.
