Possible to go under minimum balance by opening orders in multiple tabs

[twothreenine]

Let's you have an avaible credit of € 20:

1. you open an order of supplier 1,
2. in another tab you open an order of supplier 2,
3. you place an order of € 15 for supplier 1 and save it,
4. you go to the other tab and can still place an order of up to € 20 and save it
5. you have less available credit than allowed.

Possible solution: When saving an order, check if the balance minimum is still satisfied and throw an error if not?

It's not important to me, but I wanted to let you know about this.
