Both of these problems are caused mainly by your firewall and your router, with the internet speed being an additional problem. Currently, an easy way around this is simply using the /login command when in Free Play (thanks ishi) as this allows you to login without using the Client based Login, as that is the location of this problem. If the problem persists then I strongly suggest having a look at your router and firewall, and remember to check that Toribash is actually allowed through the firewall as a SPECIAL EXCEPTION, as people have just been adding it to the allowed programs list which as far as I have seen does not solve anything. Not to mention, regardless of your firewall prioritising of Toribash, your internet speed will also be a pain to deal with if it isn't to a specific standard. Currently, as per hampas mention, there was an issue with the DNS server recently (which converts hostnames into IPs), which has since been fixed and will take a while to update for users over the internet, which should have resolved this issue.

Toribash Glitch: Permanent Fullscreen
This is basically caused by toggling between fullscreen and windowed mode too much using the Ctrl + Enter method, which is a shortcut combination for fullscreen instead of going into the options and ticking the little box for it. To fix this, the only current solution (from testing anyhow) seems to be reinstalling the game. This is a bit of a hassle but as stated previously, only solvable by reinstalling as resulted from testing.
