As I mentioned earlier, the problm is with setCtlSize(), which setClientRect()
calls. The former routineperforms one client area correction too many, resulting
in the problem you report.
In setCtlSize(), locate the line hat says

posn = getPosition( id )

(close to line 19063) and replace it like this

oldBmp=w32acquire_mem(0,16)
        if not w32Func(xGetWindowRect,{getHandle(id),oldBmp}) then ?
            warnErr(Err_GRGETWINDRECT)
        end if
        posn=peek4u({oldBmp,4})
        w32release_mem(oldBmp)

This way, the dialog opens at the same place it was closed.
Anyway, you didn't need the calls to setClientRect(), since the "child" window
doesn't change size.
