PC-MAC Compatibility - PC-MAC Web Site Problems (Posted by rwhitmore)

I'm experiencing PC-MAC compatibility problems for a developed web site. The viewable information/graphics on a PC platform is fine, but for a MAC platform, the same information will not display in the correct format. The viewable text/graphics for some pages seems to shift in different directions or wraps around. The web site was designed using frames, images, HTML, and Java Script, and on a PC platform with the latest IE and Netscape browsers. I'm wondering if it's browser-related. I have verified with a MAC using the latest Netscape and IE versions and still no luck. It seems open standards for browsers are occasionally ignored. Do you have any suggestions where I can find help on PC-MAC compatibility for web sites? I certainly do not want to scrap the entire web site and start over. Thank you for your advanced consideration!
