Is it safe to run Multiple Wallet windows simultaneously? Why not?

Can you run multiple wallet windows safely? Or is one at a time better? why?

People say armory is better because multiple wallets.
Isn't it really easy to run multiple wallets on Electrum?
 You can just open another Electrum progam window right?

It's safe.

Easy? The process of creating a new wallet is a little convoluted in 1.9.8. But after you do it once you'll get the hang of it. File > new/restore to create, file > open to open
