Admin Panel not displaying correctly

My installation seems to be workingh fine (apart form these glitches). I would be grateful if anyone could help me find out what’s wrong. I am using Firefox 1.5.0.7

1. In the “Write Post” section in the box “Post” a number of small “default” type icons appear at the top of the box, and then move to the left, disappearing as they go and leaving behind a series of vertical dashes. Hovering over the gaps between these text appears sayiong things like: “Ordered list (Alt-o)”. I have a feeling icons should be in these spaces.

2. There are “strips” with writing on them to the left of the input boxes for the post and below these. They contain phrases such as: “Password protect post”. Hovering over them produces only the ability to move the strip. There is no access to any functionality.

Any thoughts? In respect of item 2., how do I fix the attributes referred to into a post?

Thanks
