LastInput.time is an Integer and m_idleTime is an Integer too. This line sometimes generates an Overflow exception, I think that this happens when both values are big negative values.

(Environment.TickCount - lastInput.time) > m_idleTime

How can I avoid that? With casting?

(CType(Environment.TickCount,Long) - CType(lastInput.time,Long)) > m_idleTime

Or maybe with this cast?

CType((Environment.TickCount - lastInput.time),Long) > m_idleTime

Thanks in advance.
