I have had my Dell Dimension for about a year. My internet explorer (6) has been functioning perfectly up until about 2 weeks ago. Now, SOME of the web pages I visit appear in larger type (resolution) and do not fit on the page. Others are normal. My set resolution is to 1024 x 768. When I try to print out the larger pages, they do not fit on the printed page either.  When I change the resolution, the standard pages get so small I can barely read them. . The pages in larger resolution then appear normal. There seems to be no consistency on which pages are smaller or bigger My virus information shows no infections. My spyware also shows I am clean.

Need some help as to how to correct this.
