You are probably working with too low a screen resolution.
Acumen is optimised to work at a minimum screen resolution of 1024x768 pixels or greater.
To change the screen resolution, you can either:
1. Select Start / Control Panel / Display, or
2. Right click any blank area of your desktop, and select Properties.
Select the "Settings" tab and change the "Screen Resolution" slide so that it points to "1024 by 768 pixels" or a higher setting. Then click OK.
If the system will not let you change the screen resolution, you'll need to contact an IT support person at your end.
