Today, I am using the latest version of glest (svn inside) for the game, found a BUG: The BUG is when I quit the game, heard the buzzing sound, I have no problem with sound card, sound card drivers are up to date. I tested five times, the problem is still the case, I use the command kill -9 completely shut down glest.bin, but still be able to hear the buzzing sound I can only restart my computer, when I tested again this time to find the the problem still occurs! titi, softcoder you can test your own, you will find this problem, thank you!
