I've been using Tixati for a number of years with great delight. I recently bought a new Dell laptop and installed Tixati. It seems to run fine except that I can't close it. When I click on the red X in the upper right corner everything goes gray and freezes. I then have to reboot. When I try to restart Tixati it says that there is an instance closing files. When I go to the task manager there is no instance of Tixati running. I have had to use Revo uninstaller to get rid of some remnants so that I could restart Tixati. I've been around this loop a number of times. It is 100% repeatable. I am using McAfee and Malwarebytes.
