Having trouble with dreamweaver as it still seems to have a mind of its own. New to code and don't really want to understand it. Finding interface very confusing as so many options. Used to corel vector based program.

It appears to me that you need to carefully examine the css styles that are applied to the buttons and weed out conflicts. On your home page, for example, both the horizontal and vertical Spry menu style sheets have been linked. You may also need to check that the background image gifs are all the same proportions. The hover background image may be narrower than the others.
