Please restart PT4 using the logging enabled link on your Start Menu, reproduce this problem and then report it via our
support system with the log file - that will help us figure out what is going on here and get it fixed for you. You can find that file by clicking File --> Show User Data Folder in the main PT4 window - the file we need is the text file called PokerTracker4 that is in that folder. If you could include a screenshot showing the missing panel that would be useful as well.
