You may be able to enable the scroll function - go to control panel and click on the mouse icon. There will probably be a tab for your touchpad, with a button marked Settings/Advanced settings, or Properties. If you click on that you may find you have an option to enable virtual scrolling.
If not, you can make the webpage font size bigger by clicking on View on the menu bar & then Text Size.
Of course if you have IE 7 it's probably set up without the File-Edit-View menu bar, so you'll have to change the settings so it shows.
On the bar where the house icon for your home page is, there should be a little cog wheel marked Tools. Click on the arrow next to it & choose Menu Bar (you may have to go to Toolbars first & untick Lock Toolbars)
