Also in the older versions you needed to change the name of your wallet.dat to wallet2.dat or something, and close the program and open it again so it again and have the wallet you wanted to load named wallet.dat, it was really annoying hence why I just have one single wallet for all transactions, which is now a problem if I want to get it audited to buy real estate or whatever since it's all within the same wallet. I guess I could have audit for specific addresses but I haven't looked into how this works yet.
