Mac Client: Race condition when entering amount to send

[pselden]

When I enter an amount to send it looks like it is doing some processing in the background before it shows me the send button (maybe it is loading the account to get a sequence number?).

However, if I type quickly enough it appears there is a race condition where it sets the wrong number of XLM to send.

For instance, I type "123" and it will briefly flash "123 XLM | SEND" and then switch to "12 XLM | SEND".
