Within a minute of launching the app it the delay between the screen and keyboard entries is so long that it has rendered the app useless.
I have a:
MacBook Pro (Retina, 15-inch, Mid 2014)
2.5 GHz Intel Core i7
16 GB 1600 MHz DDR3
NVIDIA GeForce GT 750M 2048 MB
Intel Iris Pro 1536 MB
Running mac OS Sierra version 10.12.1
Any help would be appreciated.
