We use Dell 15" laptops to access KashFlow. running windows 10.
The screen settings are
Resolution : 1920x1080 ( recomended )
change the size of text apps and other items : 125% ( recommended)
However we "loose" the top transaction line on the invoice and purchase lists.
Eg on our laptops with the screen set to show the default 10 items we see nine full lines and the bottom edge of the first transaction in the list.
We loose sight of the content top line on the list whatever number of transactions are displayed.
We can access it by double clicking on the line but as a trainer it is not a very good advert for the product to show to clients.
