Problem in level 4... bug?

[AlexandreBR]

I've tried several different combinations, and I'm not getting past this level.
I put the two "blocks", at the same time, each in its correct color, and nothing happens. What am I doing wrong?

Look at this sample screen:

Help please.

Don't know if you figured it out, but you have to jump.
Just keep switching block and keep them airborne.
