Every time you open a form (i.e., in its form_open event handler) you 
could use something like:

  ' in every "slave" form
  DIM hObserver AS Observer
  hObserver = NEW Observer(hT, FALSE) AS "mysignal"

At this point, from the main form you can raise signals that will be 
catched by your opened forms:

    ' in every "slave" form
    public sub mysignal_refresh(...)
    ...do what to do when a refresh signal is received

In your main form, when you want to refresh the other slave forms, you 
issue:

    raise refresh

You can even use formal parameters, to pass data from main to slaves.
Or you can define several types of events.

This should work... let me know :-)
