Jim, I understand your frustration. It's either a leaking wheel cylinder or an internal leak in the master cylinder. Check the fluid level in the master cylinder. If it's dropped a good bit it's a leaking wheel cylinder. If it's staying consistent it's fluid getting past the front piston in the master cylinder. That can be caused by 2 things, a worn piston or pitting in the bore. If it's pitting, get the master resleeved with a stainless steel sleeve and you won't have that problem again. I also use red rubber grease on all my brake pistons now and it helps a lot to prevent pitting in the bores. You can find it on Ebay, Amazon, and elsewhere.
