>Yeah you right, but I don´t know how do it.

if vartype(gotimer_inactivity)="o"
  * the countdonw began again
  gotimer_inactivity.Reset()
endif

The same code that you were setting the Interval needs to be modified to call Reset. However, I wouldn't recommend using the MouseMove event. This occurs too often for my tastes. The event can also occur because of vibrations of your computer's internal fan. No one is there but the mouse imperceptably moves.

Instead of the control's KeyPress event, you could add it to the form's KeyPress event and set the form's KeyPreview property to .T.. That way you centralize the call to the form and no matter how many controls you have on the form, it works.

The Timer event of the global timer needs to have code in it to log a user out. Some of the issues to take into account are:
1. Closing open forms. You could cycle through the _Screen.Forms collection to close all the forms. Ex.

With _Screen
   for lxx = .FormCount to 1 step -1
      if upper(.Forms[lxx].BaseClass) = "FORM" then
         if .Forms[lxx].QueryUnload() then
            .Forms[lxx].Release()
         else
            * you can't close the form; you need to figure out a way of exiting from the form gracefully
         endif
      else
         * object is probably a toolbar so you may or may not need to release it
      endif
   endfor
Endwith

2. "Logging" current out of your application. WHat does this mean? Give them a new login screen or totaslly exit the application.

HTH.
