macbook won't go to sleep with lid open

Lately my macbook has stopped going to sleep despite the energy saver settings stating computer sleep is set at 10 minutes. I've tried an SMC reset, but no avail. I've removed my USB 2.0 HDD to see if the issue was potentially related to it, but no changes. I've even tried to recalibrate the battery and it has done nothing for me.

I've really ran out of idea on how to tackle this issue. Any other suggestions?

Macbook mid-2007 (2.16GHz C2D, 2GB RAM), Mac OS X (10.6.4)

You don't happen to have VM Fusionware installed do you? I've seen this problem in a number of forums.

No VMs installed. I have W7 on bootcamp.

Interesting. Like I said in the original post, I removed all USB/FW devices from my laptop and still experienced the problem. I typically have a Seagate FreeAgent Go hooked up to my Macbook to store all my multimedia (movies, files, etc). The drive is formatted as NTFS so I can use it on my Windows partition and other Windows boxes. I use Paragon NTFS to allow R/W access to the external drive on OS X.

My sleep situation has been fixed by uninstalling Paragon NTFS. I figured removing the NTFS drive might expose the problem, but it took fully removing all the Paragon disk drivers for my Macbook to return to it's sleep schedule. This is slightly inconvenient but I can find another NTFS driver solution and see what happens.
