When launching PhotoMirage, the Welcome window will be the first one to display. From time to time, you may encounter a situation where the "X" button at the top right is not visible to close the Welcome window.
Here is an example where the X button is not visible.
The easiest way to get out of the Welcome window without the X at the top right, is to press ESC on your keyboard.
An alternative way would be to:
1. Click on the Welcome window with your mouse
2. Press and Hold the CRTL key while scrolling the mouse roller to zoom out the Welcome screen
3. The "X" button will appear at the top right corner. Then click it to close the Welcome window.
