Qlik sense freezing

    Hello, I am happy working with QlikSense on Windows 10, but while I'm switching between tabs between QlikSense and other tabs ( example folders, vlc ..) using Alt + Tab controls , I always mistakenly click the Start button instead of Alt, at this stage QlikSense freezes and I can't use it and I will loose any unsaved data, and to re-open it, I went to task manager and end the task.

    Any other solution?
