I know a few people have been annoyed with their edit box (place where you type) being resecured to the bottom of their chat box, so here's the fix if you're using prat:
To fix Prat 3.0 EditBox module load up EditBox.lua (Found in Prat-3.0/modules) and remove
"if Prat.BN_CHAT then return end -- Removed in 3.3.5 "
Then Find every "ChatFrameEditBox" and replace it with "ChatFrame1EditBox". This will force it stick to the main chat box on your screen and will allow you to use this module again.
On the first test it showed the background in front of the font, but relogging seemed to have resolved the issue.
