Curse Client Interferes with LoL Launcher

Every couple or so log-in attempts, when I click the giant "LAUNCH" button at the top of the screen, the window will minimize, but the log-in screen will not appear. I went to disable all process trees (that were running) related to League of Legends. I restarted the game, the same thing happened about 4 times. Finally, I decided to close Curse Client to see if it was possibly the culprit and sure enough, when I tried to log back in, I was able to.

I'm not really sure who this should be sent to: Riot or Curse, but I just want to get the word out that you may need to disable curse before proceeding into the client.
