Setting Windows text scaling higher than 100% causes the Task/Restrictions UI to clip. If there are more than a couple of Restrictions the bottom one will be cut off. The AND/OR boxes are squeezed and may disappear, and the parenthesis boxes will disappear.
Steps to repro on Win7...
1. Right-click the Windows desktop, select "Screen Resolution"
2. Click "Make text or other items larger or smaller
3. Select 125%
3. Open the Restrictions tab of a task
5. Add restrictions
6. Observe reported issue
Currently running 1920x1080 but other sesolutions didn't seem to effect it. Seems specific to text scaling.
