search term needed

when you click from the main page to an added page, the page jumps sideways to the right while loading. i remember seeing somewhere how to resolve the problem-none of the high class blogs jump between pages, but have forgotten
solution or “search term” applicable for this occurrence. if it will be resolved in the next version i will wait it out, otherwise this will be the next project after somehow completing the installion of wp–simple viewer. TIA best…skip
