Transparent skin -> drawer problem

[shinizzle]

hi community
i just registered here to ask if you maybe have a solution for my problem...
I want to create a transparent skin and i also want to include a drawer. but the drawer can be seen through the main window

drawer closed


drawer open


is there a possibility to really hide the drawer while hidden?
im not really a pro in skinning so a tutorial would be nice

thanks in advance :P
