Only works once on frontend (Wordpress 3.9)

[CodingMadeEasy]

When I try to use crayon on the frontend it works fine when I click it the first time but once I add my code and I try to add in another code block it refuses to open.

Is there a way to fix it so that I can use it more than one time?

I have the same issue too. The first time I click on the <> button it opens, but then it won't open anymore. I'm using Gutenberg plugin and a classic block to open crayon
