If you have a high resolution monitor and are running Windows 10 you will sometimes have an issue with the font of SST being to small.  If this happens navigate to the following directory using Windows file explorer "c:\\Program Files\\Superior Swim Timing\\SST Timer".  Next, left click and then right click on "SST 64.exe" and left click on "Properties".  Click on the "Compatibility" tab and then click on "Change high DPI settings".  Check the box for "Override high DPI scaling behavior".  For the Application, select "System".  Click "OK" to exit the properties box and apply changes.
