ECB Window management bug (Customize/EShell/VC-Log...)

Hi, 

I found this bug particularly annoying. Steps to reproduce:

Start Emacs (emacs shows the scratch buffer)
M-x ecb-activate (ecb windows created around the scratch window)
M-x customize (emacs switches to an EMPTY Customize buffer, the
customize stuff is inserted to the scratch buffer rather than the
customize buffer)

The same thing happens for Eshell as well(and VC-log when you hit C-x v
v on a version controled file to commit it). With ECB active, running
Eshell will cause the command prompt being insert into the buffer you
were editing.
