JavaSoft isn't specifying WS_CLIPSIBLINGS when they create checkboxes, lists
and radiobuttons (possibly others). This is the actual fix for bug 445064,
the hackaround for which has been causing bugs elsewhere.
All files in src/win32/sun/windows:
awt_checkbox.cpp line 50
awt_choice.cpp line 50
awt_frame line 80
awt_list.cpp line 49
awt_scrollbar.cpp line 57
Each line contains a WS_CHILD flag which should be changed to
WS_CHILD | WS_CLIPSIBLINGS.
