I have an application that works as follows. The page is divided into 4 frames. In frame1, we have the alphabet, each letter is a hyperlink.

When the user clicks on a letter in frame1, frame2 is populated with all categories in the catalog that start with that letter. Each category is a presented as a hyperlink.

When the user clicks on a category, frame3 is populated with all products in that category.

When the user clicks on a product, the description shows up in frame 4.

The hyperlink for a letter looks lis this:

<a href="scripts/foxisapi.dll/dcc.headings.runit?headletter=A" Target="frame2"> A </A>

In IE5, this works great. The FoxISAPI gets the listing and puts it into frame2.

In NS4.61, it opens a new window and nothing displays.

In IE4, nothing seems to happen.

Has anyone seen anything like this before? What could be the problem?
