Thanks for the help guys, I figured it out.  Took a couple days, but I got 
it.  It was a rising ground plane problem with the CPLD.  See 
http://www.xilinx.com/xapp/xapp073.pdf for more details.  I had too much in 
rush current by turning on so many outputs and combined with the relay, it 
brought the ground plane up, making my "relay on" signal look like off, then 
it would fall after the in rush and it was back on again.

Hope this information helps others, I hate problems like this.  Guess thats 
why I like digital, hate analog.

Thanks again,

Vern
