Under Windows 2000/XP:
Right click "My Computer", select "Manage"
You should see the "Event Viewer" option in the left pane. Select it and choose which log you want (probably the System log).
As to the Runtime errors: I can't say I've gotten any of them - make sure your computer is up to date (
www.windowsupdate.com ) and you have antivirus software & a firewall. If you still get the errors, check and see if there are specific programs you have running every time you crash.
