Sessions not sticking

[Chimeric]

Hey there,

I combed the forums for an answer to this issue but nothing seems to be working.

I'm running XAMPP at my current workstation, and I've just installed a fresh copy of v.1.3.4. The install went smoothly, but sessions don't appear to be working. I'll login, and immediately I'm logged back out - I can't navigate to admin CP or to user CP. I tried registering a new user but to no avail - the moment I navigate away from the page I'm no longer logged in.

Apache, MySQL, Mercury and Tomcat are all enabled. I double-checked my browser cookie settings - also enabled. There's no error being generated, and sessions are clearly being written to the database (I cleared the field and tried logging in again - a new session identifier was written to the field so that's not the problem), they're just not... sticking.

Any insight?
