[JAVA3D] Problems with 2 Frames

[Marco Lombardo]

I have a little problem with a program in my project. I have a JFrame with contains a Canvas3D (in a JPanel). I have used 4 JButton in this JFrame. When I push a JButton of this,  sometimes happens that the new JFrame (that must be shows on the first) is shows badly (it's like if the PC wait i don't know what). Then, in the program I have removed Canvas3d first that I pushed the JButton and also, I have increased the Memory of VM (java -mx64) : I have obtained good results, but the problems sometimes happens again. It's strange. Can I have a help? Thanks Marco
