Any reason you're using frames? They went out of favour on the web over a decade ago. There are so many better ways of doing things on the modern web.
John's right. Frames are so horrible, the W3C stopped supporting them in HTML5.
If you want navigation that works well in all web devices & browsers, don't use Frames/Framesets.
Use a DW Template or Server-Side Includes for sitewide navigation.
John and Nancy,
A great BIG thank you for your direction. When I originally designed our class website a number of years ago, frames were much more popular. After reading up on creating templates, we'll soon be making the transition.... but first I need to sift through all the pages created through the years.
