When you open a behavior panel of an entity, at a bottom you will see things like flag 1,2, 3, and soo on. When you add action like PiBiped01 it will display half çà what is writen and the other half gets cut of because the size of the window is too small and you can't resize it. It makes work in WED a little bit difficult when you can't see what you are clicking.

Grab the top of the behaviour panel and drag it out to the middle of your work area. Here's an image of the problem and when you drag it out. http://www.ehostwebsites.com/screenshot.html
