- Right click on your Desktop & select 'Properties'
- Click the 'Settings' tab at the top right
- Look to the lower left for the slider. Increase the resolution to at least 1024x768 by dragging the slider to the right.
- Click Apply, then Click Ok
Hopefully now you'll be able to see everything. You might also need to restart your browser. Post again if you're still having problems.
