Reproducibility:
Go into full screen mode and then choose My Cards, then either My Collection or My Decks. When you either edit a deck or look at your collection, the search function won't accept any text. It works fine in non-full screen mode.
Recap:

Description:
I'm not able to search for any cards in my deck or collection while I am in full screen mode. I use Firefox 23.01. I can try other browsers if you want me to, but I don't consider that a solution because having to change browsers for a single game isn't right.
Setup:
No setup needed
Screenshots:

This is a Flash limitation.
In full-screen mode in any flash game, you can't input any text.

I found some articles that say that Flash 11.3 does do full screen text, and all they have to do it set some flags. Here is a sample one:
