I am having problems with a back button on a frames based site.
I have Four frames one contains a back button, referencing the history object for the main frame.

It works fine in netscape, but in IE it is odd!(tech term!). When accessing pages on the same server it works fine, however if the page loaded in the main frame is on a different server the browser returns its annoying page can't be displayed error message. The browser toolbar back button works fine, also it works fine if I type the "javascript:history.back()" into the toolbar address.

What is going on!!!!
Any Ideas - Thanks for your help
