HELP! - New MC leaking - from TOP?

I replaced the non-power brake master cylinder last year, but just got the truck on the road last month. After I drive it, I get a load of brake fluid all around the sides of the MC, dripping down on to the steering shaft (and wiping out my new paint @#$^%).

If the truck just sits, theres no leak. It's definitely coming out of the top; I can see it seeping from under the rubber gasket; it's not leaking where the brake lines screw in at all. I've cleaned and sanded the rim of the MC and the rubber gasket is new, clean and flexible. The bail is tight; need a screwdriver to pry it loose.

I'm out of ideas here, short of using Form-a-Gasket, but I suspect there's something else wrong.

BTW: I started out with the brake fluid level pretty near the top, but it's now about 3/4" down, and it still leaks....

TIA
