The Problem: when you try to open charts or a matrix there is no "ok" or "cancel" buttons. Your buttons are hidden.
This is the solution to fix that issue.
(Windows 7) Step one:
Step 2: Go To Display
STEP 3: Choose 100%
o Smaller - 100% (default). This keeps text and other items at normal size.
o Medium - 125%. This sets text and other items to 125% of normal size.
o Larger - 150%. This sets text and other items to 150% of normal size. This option appears only if your monitor supports a resolution of at least 1200 x 900 pixels.
3. Click Apply.
WINDOWS 10 Solution
