How to Disable the output log?

[Vorpal86]

When a game starts up, how do you disable the yellow log text that appears? This is a bit annoying for the most part because i have tried looking for a way to disable it but nothing. I want to make some videos with fraps and this gets in the way.

Also, where are the dolphin emu docs for using the emulator and describing what functions do what and what hotkeys are used. Aside from trial and error. I don't notice any guide or anything included.

thanks .
