My company uses MSVC6 for all development. I've recently been involved in a project to upgrade to VS2008, so I haven't touched the older compiler in several weeks. This morning, I updated the old compiler's SVN checkout and ran a build, and suddenly every time it finishes building a project, it beeps the PC speaker. This is rather annoying, since our app consists of over 70 projects and builds run for about 30 minutes. I can't figure out how this got turned on. I also can't find any option to turn it off. Does anyone know what's going on here? I suppose as a last ditch effort, I could cut the wire to the PC speaker, but I'd really rather not have to do that. Also, I like it to beep when I get an email (which is far less frequent). There is no sound card in the computer, so the PC speaker is the only sound output device.
