A patch for a flaw in "Windows WM_TIMER Message Handling", released with "Microsoft Security Bulletin MS02-071" (Q328310), causes random crashes (blue screens of death) on WindowsNT systems. Besides annoyance it forces uninstallation of this patch leaving systems vunerable for the flaw. Microsoft was contacted by me today. Others has contacted MS earlier. Crashes occur at about one in a day rate (on office computers).
