mouse movement supersizes open window in safari
When using Safari 18.0.1, often my unknown movement with the Apple mouse will supersize the open window. Often the new size will be so large only a quarter of the content will now be visible. I have to click on View, scroll down to Actual Size and select that option to return the window content to the previous normal size. This effect is like Zooming In. I have no idea what small movement of the mouse or particular touch causes this. It is very annoying when I am working with a Safari page. How can I turn this effect off? What mouse action causes this enlargement?
