I will test this latest revision with my
prj files and let you know what happens.

I see that the IDE is at 1.0.2... I'll try that version and let you know.

I've got sample prj files! I don't see a way to upload the files to the
SF repository.

The bug is there, and you may have got my comment by email.
Text handling routines for RichEdit controls have been modified somewhat to
accommodate RichEdit v3.0 (remember, the controls would hardly work on XP with
0.60).
Probably the lib is using a non extended WM_ or EM_ message at some point - a
remainder that the message architecture is still largely the one of the 16-bit
win.exe -. I'll see if I can post a fix tonight, ie 12-15h from now, else this
weekend.

I think I got it. Locate the getData()  function in win32lib.ew and replace the
starting if branch like this:

if ctrl_Type[ id ] = RichEdit then
        -- return selection
        buffer = w32to_memory(0,ID_CHARRANGE, {0, -1})
        VOID = sendMessage( id, EM_EXGETSEL, 0, buffer )
        result = w32fetch( buffer, CHARRANGE_cpMax ) -
                    w32fetch( buffer, CHARRANGE_cpMin )
        w32release_mem(buffer)

        if result > 0 then
            if equal(WC_RICHEDIT,WC_RICHEDIT50) then
buffer = w32acquire_mem(0, 2*result + 2 ) --  add 2 for '/0'
                character.
                iLength = sendMessage( id, EM_GETSELTEXT, 0, buffer )
                text=repeat(0,iLength)
                lmh=buffer
                for i=1 to iLength do
                    text[i]=peek(lmh)+256*peek(lmh+1)
                    lmh+=2
                end for
            else
buffer = w32acquire_mem(0, result + 1 ) --  add 1 for '/0'
                character.
                iLength = sendMessage( id, EM_GETSELTEXT, 0, buffer )
                text = peek( {buffer , iLength})
            end if
            w32release_mem( buffer )
        else
            iLength=getCharacterCount(id,0)
            buffer=w32acquire_mem(0,iLength)
            lmh=w32to_memory(0,ID_GETTEXTEX, {iLength,GT_DEFAULT,CP_ACP,0,0})
            iLength=sendMessage(id,EM_GETTEXTEX,lmh,buffer)
            text=peek({buffer,iLength})
        end if

So it wasn't a wrong messahe, but a wrong buffer length with the newer RE
controls.
Please report whether this fixes the issue for you. I'll update the bug
accordingly.

CChris

Note: all fixes are now going in the 70.2 version, which discontinues support
for the onXXX syntax. I'll upload it when a couple more bugs are reported and
fixed.

Strange, as I can run your test file with n=10000000 without a crash... I'll
check this further, but there is hardly a clue abou the origin of he problem.
Emailing you the whole distribution, it may help.
