We apologise to any users affected by the some of the tick boxes becoming unusually large following an update to iOS. There is an update going through the App Store which corrects this issue.
The problem at the moment is that Apple are not allowing Apps to be approved which contain drug calculators, unless they are released by the drug manufacturer or meet certain other criteria. Unfortunately this applies to Apps which have already been released and are being updated.
We are currently working with Apple to resolve this issue, and we hope that it can be resolved soon. This is very frustrating for us as we have a patch which fixes the simple problem causing this issue, which works well and has been tested, but we are unable to release it at present.
We apologise again for any inconvenience. It annoys us and frustrates us!
