2013-10-01 Scientific Calculator B1 and iOS7


In some cases user have reported crashes after installing iOS7. Our investigations showed us that this seems a bug in iOS7 and is outside of our possibilities.... but it's not a big thing:


Workaround: in such cases do the following 


a) remove the Calulator from Springboard and launch new or

b) restart the device or

c) reinstall the calculator.


One of the three steps  will work definitly.
