Why does KOL Mafia beep at me every session?

Every once in a while, it beeps at me. It's done this for months, and I have no idea why. There is nothing in the CLI. It has happened when auto adventuring and when playing directly in the relay browser.

chatBeep is false.

Presumably it wants my attention for something. But it's like seeing a sign posted in the middle of a park, "DANGER". Without any idea what the danger is, the sign is ignored.

In ChatParser.java, chatBeep controls whether Toolkit.getDefaultToolkit().beep() is called. That is the only occurrence of beep() in the Mafia source. Perhaps there is another beeping function, but I'm not familiar enough with Java to know how it is called.

Could this be an OS dependent thing? Which one do you use?

XP 64-bit, and 64-bit java.

This has been happening to me as well. Vista 64-bit. JRE-1.6.0_22, in the x86 folder so assuming not 64 bit.

I have win 7 64-bit and 64-bit java and I also get the once-in-a-while-for-no-reason-at-all beep.
