Why does Y/A tell me that they're taking a 'coffee break/breather' when I am trying to submit an answer?

Isn't it Frustrating?? You give a LONG really GOOD answer then it won't allow you to POST! I had that happen a couple of times and TRIED to Copy and Paste and it wouldn't accept it, It would just say 'Taking A Breather" Again, so I started Shutting Down my computer every so often and re-booting and it hasn't done it since...Try It!!~~Luv Ya~~Shell~~
