Unwanted application icons showing on unity taskbar

http://askubuntu.com – I installed my Ubuntu 12.04 desktop after a dependency loop hell. After I re-installed the Unity panel shows all application icons whenever the app is loaded. For example I can now always see VMware and X-Chat where on every previous install these icons never showed no matter how much I wanted them too sometimes. These indicators are starting to fill up my taskbar and was wondering how to make them go away. For example I want Thunderbird, Empathy and X-Chat to be able to be closed to the messaging menu like they did in all my other previous installs. Also I have X-Chat i (HowTos)
