GIMP :: Preventing Closing Dock By Mistake?

Sometimes Iwould close by mistake a tool dock by clicking alt-F4 a little toofast, while the dock has the focus, but I thought it was the image(and I wanted to close this image). Then the dock configuration (whichtools were set there, which tabs,size and position of the dock andtabs, etc.) is lost. So of course, I can always recreate the dock,reposition/resize it, set the right tools inside. But that's boring.

would therebe an option right now to prevent the tool docks from closing by theusual window-close event (so you could close them by the dock menuexplicitely, but not by quick shortcut for instance)?
