   Tried again after applying patch (I think it was already applied, but 
did it again..) still fails - worth a try tho.

That still didn't work for me but it does work when I cut out support 
for RichEdit 5.0.  You can check to see what version you are actually 
using by checking the value of WC_RICHEDIT.  Anyway, when I edited 
w32dll.ew as follows, it worked fine:

global constant
    riched32    = 
registerw32Library({"riched20.dll","riched32.dll"}),--{"Msftedit.dll","riched20.dll","riched32.dll"}),

   -- Rich Edit control
    WC_RICHEDIT10       = "RICHEDIT",
    WC_RICHEDIT20       = "RichEdit20A"--,
    --WC_RICHEDIT50       = "RICHEDIT50W"
global sequence WC_RICHEDIT

vw32Libraries[riched32][1] = linkDLL(vw32Libraries[riched32][2])
if vw32Libraries[riched32][1][1] = 1 then
    WC_RICHEDIT = WC_RICHEDIT20--WC_RICHEDIT = WC_RICHEDIT50
    
elsif vw32Libraries[riched32][1][1] = 2 then
    WC_RICHEDIT = WC_RICHEDIT10--WC_RICHEDIT = WC_RICHEDIT20

else
    WC_RICHEDIT = WC_RICHEDIT10
end if

Maybe the lib shouldn't try supporting RichEdit 5.0 until we need some 
particular feature of 5.0.

I'm starting to suspect you are right. It looks as if the new RichEdit
stores text as wide-characters (Unicode utf-16 encoding). I'm still
looking into it though. I can now read Rich text wide characters but 
I can't seem to get the Find part for them working.

I suggest that Jonas is not actually using Rich Edit 4.1. That version
seems to only support Unicode utf-16 encoding and thus win32lib
will need to cater for that. I've now got getSelectedText() and
findText() working for utf16 but I need to check out some other
routines as well.
