Some premium Windows 10 devices including Surface laptops and tablets use high resolution displays. If you own one of these devices you may need to adjust your display settings if apps aren't appearing correctly.
In Control Panel > Display > Set a custom scaling level
Scale should be set at 100%
You can also edit an application's Compatibility Properties.
Right click on your SalesPartner Icon and open Properties. In Compatibility, Select Disable display scaling on high DPI settings. Click OK and restart SalesPartner.
