Let me quote someone's reply in a forum to a user having the same problem with another Java application: If an action executed in a Java application reboots your computer there is a problem with the operating system installed on your computer. A Java application cannot reboot the computer if it does not execute native code which reboots the computer and X does not call any native code. «Native code» meaning any part of a program that isn't written in Java, and «X» being Sketcher in this case. This is a problem I've never been able to reproduce. Install CPU Burn-in (http://users.bigpond.net.au/cpuburn/) and run it for a while. If this causes your PC to crash, you need to speak to your PC vendor. Since Sketcher relies on JTablet (which *does* call native code, but nothing that should reboot your PC) for pen pressure support, you could try removing that if you installed it. I doubt that it is the culprit. Thor
I'd also like to add that when most people report that their computer spontaneously reboots, what has actually happened is that Windows has «bluescreened». Because non-technical users have no use for the data presented in a BSOD («Blue Screen of Death»), WindowsXP is by default set to omit displaying this screen.
What most users do anyway is to reboot, so it simply does it for you. This has the unfortunate side effect making your computer seem more erratic («What? It doesn't even bluescreen now. It just suddenly reboots?»).
Bluescreens can be re-enabled like this:
- Go to the Control Panel and engage Classic View.
- Open the System icon and go to the Advanced tab.
- Click Settings under Startup and Recovery.
- Uncheck Automatically restart.
- Click OK until you're in Control Panel.
- Close Control Panel.
Be sure to take notes when these bluescreens appear, especially of the main text. Later, you can Google this and find information on what may have caused the bluescreen. This information can be useful when calling your PC vendor's phone support as well.
I think that is all.
Thanks,
