Can't upload images with Magento 1.4 on Windows/IIS

Everything else works in Magento 1.4 but I can't upload images. Running on Windows/IIS. I know it isn't officially supported but seems odd that everything works but something as simple as image uploads.

Tried updating the media path and that is correct. Also updated permission开发者_如何学运维s on directories, but nothing has worked.

Any other ideas to get this to work?

thanks

I've seen this problem happen when you have Basic Authentication on the entire site. Everything works, except image upload. I didn't find a solution other than removing the basic auth temporarily when needing to upload images.

Have you tried this? http://www.magentocommerce.com/boards/viewthread/19925/ (essentially set permissions on TEMP directory where images are saved during upload)
