Problem with Photoshop SDK example plugins

Hi,

I would like to write a filter plugin. So I have downloaded the Photoshop CS2
SDK and I have compiled all the example filter plugins from it. Now when I use
an additional directory for loading the plugins to the Photoshop CS2. Only 3 of
7 show up. I am using Windows Vista.

Does somebody know what I am doing wrong?

Thanks

Apart from the obvious, no.

Vista brings a bunch of new headaches for people using plugins, including
"entry point not found" and memory bugs which XP/OS X users don't
encounter.
