I'm running XPsp3, and for me CTRL-R, CTRL-L, CTRL-E and CTRL-R certainly do
work in read-only mode.

I just tested, I read-only mode, CTRL-+ (superscript), and it was indeed
blocked.  Hmmm...

It certainly does seem that the read-only feature is only partly functional
(which feels more wrong than not functional at all). I wonder if thats a
normal bug, or a bug-with-seniority (aka: feature). :-)


Bottom line, its not a case of me not knowing and not being able to find the
setting for disabeling the text-formatting keys, it looks to be a bug.

Bummer.  Now I have to go and subclass that control to catch and filter the
WM_KEYDOWN messages.  :-|

In my resource-definition I'm specifying "RichEdit20A" (text, not a 
constant).  Although, thats using an XPsp3 2008 RICHED20.DLL, which contains 
both the v2.0 and v3.0 versions.
