[xmonad] 'sink' on dmenu

[Maurí­cio]

Hi,

I'm using this as my manage hook:

mH = ( ask >>= doF . sink )

I don't understand much about X and xmonad. I
read 'sink' clears the float flag from a
window. However, some windows (like the one
from 'dmenu') still do not appear as other
windows managed by my layout.

Of course, this is the way it should be. But
I would like that all (even 'dlmenu') windows
be managed by the layout manager.

Is there, maybe, some other flag I should
clear or set?

Thanks,
Maurício
