My system is
Win Server 2003 w/SP1
IIS 6.0
PHP 4.4.x
MySQL 4.1.x

I've read the docs, the faqs, and searched here, and cannot find the solution.

I'm running many other PHP apps just fine. I'm not having any problems with PHP, MySQL, or IIS.

I just unzipped the 1.3.7 Zen Cart.

I ran through the configuration. That went fine. I checked, and my configure.php file is dated 3/2/07 (today), so the directory was writable for the installer.

I go to the admin screen: login with my admin username and password. The resultant screen is just blank.

Looking through the filesystem, I see "admin.php" in the admin directory. I type it in manually into my browser, and the admin screen does load. Hit the logout link, and I'm redirected back to the login form.

Login again, (starts at login.php), redirected to index.php, gets stuck on index.php.

I'm thoroughly confused, because some redirects work, some do not.

I am able to add products/categories/options/etc. to the catalog, but the fact that I see this oddness with redirecting makes me nervous about what else might not be working as expected that I've yet to discover.

Thanks...
