My WinXP SP3 work laptop locks itself (as if pressing Win+L) after about 15 minutes of inactivity. The irony is that I need to watch presentations that take more than 15 minutes, or I'm in online meetings where there's no need for mouse/keyboard and it pisses me off that the screen locks. I haven't found a freeware tool that would disable this bonehead security system (it's not just the screensaver, that is set to "(None") already), but:
If I have WinSCP connect to an unreachable host, it will enter some sort of hung state (the connection dialog doesn't repaint itself), and the damn screen lock doesn't activate! That is great.
Now, is there a way to extract this functionality into a tiny utility to prevent the screen from locking? This would be a really useful tool, as it doesn't fake any keyboard or mouse movement, and I've seen requests for such a utility on various forums (<invalid hyperlink removed by admin>).
Also, it might be a good idea to fix that behavior in WinSCP.
