Safari trackpad commander

macOS & Mac Apps

hello folks
i just bought my macbook air 11 inch less than a week ago
since i updated to Yosemite, i have a silly problem
when i open a webpage on Safari, it works well. however, when navigating the track pad to choose headings, links etc. the page disappear suddenly and there's no way to open the tap again. i have to quit Safari and reopen it again
does anyone face the same issue? and is there a solution?
