Error when Metamask is locked

[montsamu]

In latest git code (not live web) receive several errors when attempting to view the dev fund with a locked Metamask, resulting in a blank page. The first of these is:

Error: Please pass numbers as strings or BigNumber objects to avoid precision errors.

228 | withdrawalAmount = withdrawalAmount.toFixed(2);

Even when I changed to use String(this.state.contract.balance) there was a later error, which led me to figure out that my Metamask was locked.
