Everytime a tab is clicked the Enter Network Password dialog is displayed,
though entering a valid userid and password just redisplays the dialog,
clicking cancel displays the page correctly. Everytime a postback is done to
the page the results are the same (Enter Network Password dialog is
displayed).

The folder and the page with the tabstrip uses ssl & basic authentication,
while the majority of the web site does not.

Can someone tell me what could be causeing this problem, and what can be
done to fix it?

Well I fixed my problem, I can't believe no one has had this problem.

In TabStrip.htc the f_Init function has the following lines of code
var cacheImageDef = new Image();
var cacheImageHov = new Image();
var cacheImageSel = new Image();
cacheImageDef.src = sepDefaultImageUrl;
cacheImageHov.src = sepHoverImageUrl;
cacheImageSel.src = sepSelectedImageUrl;
If you don't set these properties in VS for the tabstrip control ie attempts
to open a file called NULL in the same directory as you aspx page.

Instead of fixing this in the htc file I decided to create a file call NULL
just incase this problem resides else where.
