I looked around the web, but couldn't seem to find anyone else talking about this. Is there a way to make it so that Voobly doesn't pop-up as soon as I turn on my computer? I don't use it all that often, and it's kind of a pain having an application slowing down my startup speed just so I can x out of it (I have a really slow computer. The first time this happened, I wasn't expecting it, so I had clicked on my internet browser already. And the weight of both the browser and Voobly so early in startup crashed my computer. So now I have to wait a few minutes so I can close Voobly, and then startup the browser).

Press CTRL+ ALT+DELETE and open the task manager. Open the 'Autostart' tab.
Scroll down to Voobly and disable it's autostart.

Alternatively,
