There is a new thread in the forum that might contan the answer: "As Cagsil noticed, we are in the process of testing out some changes to our text capsule editor. It's been turned on for a small number of specially selected trial users for a couple of days already, and now it's available to all. In order to switch, just change the settings on your profile settings page under my account.
As part of the change, we upgraded to a recent version of tinymce, which may help with some browser compatibility issues. You probably won't notice that change, but here are the things that you may:
Resizable edit area - After clicking "edit" on a text capsule, you can hold your mouse down when it is over the lower right corner of the edit box and drag the corner in order to size the edit window comfortably for your screen.
Word count - the number of words in your text will appear at the top of the edit dialog, while you are editing a text capsule."
Hope this helps you Horseback.
