Go under Quick Links-> Edit Options. There are some visible options in there that affect being able to see signatures and also images. Make sure you can see those. There is also an option that says how many posts will display before going to the next page. I changed mine awhile ago and it's really been nice.
If this isn't the problem then tell us what browser you are using and we'll see if we can help. I provide production support for a couple of web applications and might be able to figure it out. I'll try anyway.
