F5 not working on lockup mode : can't even close the window! (Standalone Client)

When the game locks up completely on Standalone, you have to shut down Tanki from the

Task Manager - unlike the original "an error has occurred" (using F5 still costs a life!), this is a hard lockup that cannot be exited much less re-entered. There is obviously a basic flaw in the F5 patch that is not preventing the "escape" and reconnection to the server.
