first post

I am new to wordpress and I am trying to get my first blog started… when I go into the administration panel, and og to the Write Post page, I can put a title in the title field, but when i try to put a post in the Post field, I don’t get a cusor, or anything and I cant write anything in there… if I drop down to the Tags field, I get the cursor and I can put something there…. I’m probably missing something, but I cant figure it out…
thanks for you help
