TestRenderToTexture does not work

Hello

i just gave a test to TestRenderToTexture.java

the onlything i get is a gray cube in the middle of the scene

i got an nvidia Geforce 8400 GS

is it compatible with this card ? wich is a few years old (i think)
is it possible to make it work ?

thx

i also tried to create a test project cos i read that it was possible to select testrendertotexture as a test case but i got no option to do that
so i tried to update the platform, but, once again, there is a network problem
