site builder functionallity

I seem to have to spend more and more hours every month to update our page. Last few months the site builder page is only about an inch or inch and a half at the top of the screen to edit and work in very hard scrolling up and down in a small area.  Now I am trying to insert a JPG image for this months calendar and it does not get put into the text of the page as it used to.  Does nothing and leaves the blank line there.  I am using compatibility mode but does not help.  Also cannot update a distribution list in the email account any more unless I use an old notebook with an extremely old version of IE.  Need the ability to work with up to date productls.
