[JAVA3D] Why can not I run my Java3D file in Java1.4

[Guang Bin Liu]

Hi Friends:   I can run my Java3D file in Java1.3 and Java3D1.2.  However, everytime when I run the same file after installing Java1.4 and Java3D 1.3, I could not get any JButton or Button responding to my click.  Why?  Please help!   Thank you!   G.B. Liu
