No it's not a common problem. But it may happen if either the Java version is not up to date or there's something wrong with the installation. I'd suggest u try to get the latest update of Java. If that doesn't work, try reinstalling LW. Failing that u could try to uninstall Java & reinstall. Failing that/alternatively, try the
beta version 4.1.5 (click on links) And/Or see this thread:
