Jgross, I have the same issue. I can make it small, medium size but not the large size. there is no option to expand it when I click on it, only the little arrow to make it smaller.
Ok,for what it's worth I thought that I had an expanded version yesterday,before I did a hard reset.(bluetooth causing the phone to freeze). The phone functioned beautifully and did a complete restore. I just un-installed the app and re-downloaded it from Nokia favorites and it expands perfectly now.
