jonas, i received this from derek some time ago:

the standard is to trap the TAB kay and not pass it on to the keypress
handler.

There is a trick you can use though. It will mean that you will ahve to do
your own tab processing though.

If you do this ...

   VOID = setTabCodes(0)

then no key will cause tabbing between the controls - plus the TAB key gets
passed through to the keypress handler.

Alternatively, you could do ...

   VOID = setTabCodes(VK_F8)

to make the F8 key become the new tabbing key.
