Why does my keyboard sometimes lock up on Windows 2000?

According to Microsoft, the Windows 2000 keyboard driver may or may not handle toggling NUM LOCK, CAPS LOCK, and SCROLL LOCK correctly; this can cause the keyboard status to be incorrect or cause the keyboard to freeze.

To fix this problem, install Service Pack 2 for Windows 2000.

If you do not want to install Service Pack 2, here are two possible workarounds:

• In the Session Options dialog, under the Emulation / Modes category, select the "Application keypad" option instead of the "Numeric keypad" option.
• In the Session Options dialog, under the Emulation category, set Keyboard to "Default" in the Emulation group
