The Wallet module causes crash on W8 Pro. This issue may come up if we turn on / off the Wallet module. Otherwise, this is a useful feature, it would be a detailed description. Unfortunately, if you have set a master password, we can not subsequently to modify or delete. In case we turn off the module Wallet, next time we see that it is on, so this certain switch has no effect. I think this behavior is related to the caused error. In addition, the master password request can not be adjusted so that instead of to log on to Windows, open the browser, on the contrary, it will always return to the default setting.
