So we can investigate this please
enable logging, reproduce this problem and then send your log file to us in a
Support Ticket. You can access the 'Logs' folder with the log file by clicking 'File --> Open User Data Folder' in the main PokerTracker 4 window and depending on your Windows settings it will be a text file called 'PokerTracker4' or 'PokerTracker4.log'. Also include in your ticket the version of the iPoker software Betfair is using (displayed in the lobby) and what resolution your display is set to.
