Ah, I guess you also meant <delete> above, not DEL.  With <delete> I
also see what you reported.  This is indeed different from the behavior
of <delete> with an active (highlighted) region.

But the standard binding of delete-char is C-d, which you (meant to)
report above behaves like <delete> (assuming you meant that key instead
of DEL); see also your Subject header.  Whereas, as I said, I do get
deletion with C-d.  So the unexpected behavior in cua-mode is (just) with
<delete> (bound to delete-forward-char), is that what you're saying?  If
so, I agree (assuming, that is, that <delete> should behave the same
with rectangles in cua-mode and with active regions outside of cua-mode;
I don't know, since I haven't made much use of cua-mode).
