>I tried to implement this timer (I used this code and not the one you sent me), but I seem to have the exact same problem as I am having with the VFP timer. When I minimize the VFP application and later maximize, the login form is not shown - e.g. it seems like the timer is not firing when the application is not active.

It might be VFP -- possibly when it is minimized no code will run. Have you tried to set a breakpoint in the OnTimerInterval method? You might try sending output via SET DEBUGOUT to a file as well. My guess is that VFP is not running any code; the API would still fire since it is outside of VFP.

You might have to have an outside monitor that is running in the background...
