  21  * FIXME: The whole concept of handling unicode is badly broken.
  22  *      many hook-messages expect a pointer to a
  23  *      OPENFILENAMEA or W structure. With the current architecture
  24  *      we would have to convert the beast at every call to a hook.
  25  *      we have to find a better solution but it would likely cause
  26  *      a complete rewrite after which we should handle the
  27  *      OPENFILENAME structure without any converting (jsch).
  28  *
  29  * FIXME: any hook gets a OPENFILENAMEA structure
  30  *
  31  * FIXME: CDN_FILEOK is wrong implemented, other CDN_ messages likely too
  32  *
  33  * FIXME: old style hook messages are not implemented (except FILEOKSTRING)
  34  *
  35  * FIXME: algorithm for selecting the initial directory is too simple
  36  *
  37  * FIXME: add to recent docs
  38  *
  39  * FIXME: flags not implemented: OFN_DONTADDTORECENT,
  40  * OFN_ENABLEINCLUDENOTIFY, OFN_ENABLESIZING,
  41  * OFN_NODEREFERENCELINKS, OFN_NOREADONLYRETURN,
