Can't stop the dock icon bouncing when there is an "alert" from Thunderbird
I'm using Thunderbird 2.0.0.14 for my email. Is there a way to stop the dock icon bouncing when there is an "alert"? These happen relatively frequently in connection with my Yahoo account, and every time the icon bounces until I go to Thunderbird and click "ok" on the alert box. This is slowly driving me nuts. I have disabled the "animate dock icon" setting for new mail, and for my whole system when programs start or open, but it hasn't had any effect on the behaviour of the icon with regards to alerts.
Thanks.
