strange bugs and captcha fail

Hi,

First of all many thanks for this great plugin !

I use it with all in one event calendar, works very well.

I don’t understand why the captcha doesn’t work :

And why the booking button (“demander un devis”) is inactive in the agenda view, but become active if the visitor click on the read more link then come back to the agenda view :

Hope you can help me.

Thank you again, and sorry for my english.

regards
