The entry text is not displaying properly while using 2.7.1 with Mountain Lion
There is a known bug with using 2.7.1 with Mountain Lion that causes an entry and text display issue. We're working on an update to a new version that will fix the issue. The new version will be available for free to all 2.7.1 users from the Mac App Store. For now, the manual workaround is to set your Zoom level to 100%.
