Problems with sound preferences

[DeMus]

When I open the sound preferences window, it is so tall the bottom part sticks out of the monitor, meaning it is not visible. I can't reduce the size, this doesn't work. I can't reach the text and items which are at the bottom of the window. When I maximize the window, whenever I click somewhere in it the part of the window which is visible changes:
I have the top part visible, click, I have the bottom part visible, click, I have the top part visible, etc.
I can't select anything anymore since as soon as I click with the mouse the other half of the window comes up.
I have to stop it now using a right-click on the button in the panel since the close button reacts the same as all other parts of the window.
Attached the window before maximizing it. You can see the bottom part is invisible and so unreachable. This happened with the "normal" Lucid and now the second time with Ubuntu-Studio 10.04. I did a complete re-install but the same happens.

Even better would be when instead of the sound preferences I would get the mixer visible when clicking the loudspeaker icon. Sound preferences is something you set one time but a sound-mixer is something which settings change when using sound.

Nobody else has this problem? I even did a complete re-install with making a completely new home partition (so no old data was left behind) and I have this problem again.
Who has any idea what this can be?

What do you need to use sound preferences for? You might be able to use alsamixer instead.
