We do have some known issues with .it Zoom. We are working on them. If you are willing to help us, you can do so by restarting PT4 using the Logging Enabled link on your Start Menu and reproducing any problems you may have. Then please send us the PokerTracker4.log file via a
support ticket so that we can investigate this further for you. You can find this file by clicking File -> Open User Data Folder in the main PT4 window. The file we need is the text file called PokerTracker that's in the folder that appears.
We can also make sure you receive automated notification when a new PT4 beta is out with a fix if you create a ticket.
