Hello gleenibm_031,

Can I ask what your regional settings are? We have another user that is experiencing the same issue and we have been unable to reproduce it here.

Thanks.

Hello gleenibm_031,

Could you please check your Windows DPI settings? If it is not set to normal could you please set it to normal and try again?

Thanks.
