I've done some additional tests: It does *not* happen with Ubuntu's emacs23 
(23.3.1). Just for cross-checking, I ran Win32 emacs 24.2 once via wine and 
once in VirtualBox+WinXP, in both cases no bug.

It *does* happen with Ubuntu's emacs24 (24.1.1), which is where I first noticed 
the problem. It also happens on all  X toolkits (gtk, gtk3, athena, lucid).
