I have noticed that when I scale my Mozilla Firefox Browser v30 below 100% (which I know some users do) it cuts off part of the calculator's frame. I have tried adding width % in the frame in which the calculator appears, but it makes no difference. If browser scale percentage is below 100%, the calculator is chopped off on the right and bottom. Any fixes you can think of? I'm posting a sample with browser at 90%. I am using Moodle 2.6.4 the theme is essential 2.7.1.
