Mine returns to previous settings like wpoll and I thought that was default but I probably coded it that way as well. Actually my re-start settings don't take on changes until they have been used a couple of times so you can make a one time change and it will still re-start at the previous restart settings until you change it a second or third time. I think that's all in the key programming and is also tied to each key accordingly. Works perfect for me anyway.
