How do I fix HZTool warning: "Too many drivers!"?

[Kolgar]

After a weekend of testing new video drivers, my HZTool now gives me this message on startup: "Warning: Too many drivers detected!"

Thing is, I perform a clean driver install every time I switch drivers. So I don't know what this message means, or how I can fix it.

Anybody have any ideas? Thanks in advance.
