I upgraded all my mIRCs to 6.21 , however NONE of them are working properly with Beep, such as /beep 1 1 , or just a simple /beep 2 . However, if you use backspace too much, and there isn't anything to backspace (such as I typed 1 character, and backspaced 2 chars) I still get the 'beep' tone.

Any ideas as to what happened ?
