Spellbreak 

Spellbreak takes advantage of the fact that we can now get more accurate interrupt data with 2.4 and lets you track how many seconds an enemy will be locked out of specific schools and not be able to cast anything from them.

Handles every interrupt and silence in the game, if someone is silenced it'll show a lockout for all schools and if the silence is removed early then the timer disappears.


Includes alerts for when a tree is locked, and when it's unlocked you can send the alerts to chat frames, party, raid warning and combat text mods.

For bug reports or feature suggestions
From now on I will be using the portal WoWI provides for bug reports, as it is much easier for me to manage with a lot of addons and limited time. You can find a link below the download button, or at http://www.wowinterface.com/portal.php?id=269
