I once tried to paste something (Ctrl+v) and i think i may of miss clicked, and then toribash went Fullscreen, i dont like fullscreen and even when i do /opt fullscreen 0/1 it doesn't change anything. I also tried going to the menu ->options and it also didnt work, after re-opening toribash it's still in fullscreen and the most annoying thing of all is that when i try to click on a joint to move, it registers as a click above my cursor. Picture:

ctrl+enter
this toggles fullscreen mode off and on, you probably press enter to type something with ctrl already held down.

Go to options, disable fullscreen, edit your screen resolution.

Or alternatively, press ctrl+enter and type the "/resolution [width] [height]" command

Not working. It seems to almost work cuz my screen goes black but it just goes back to fullscreen again?

Sir, i tried that, wont work.

I had this problem. modify the resolution while in fullscreen. ctrl+enter then when its not in fullscreen set it to a smaller resolution. that should do it. if not then after modifying the resolution in fullscreen, disable full screen then re-open toribash.

It's a lot to do but it should fix it. It did this for me and I had to have it fullscreen then I just kept spamming ctrl+ enter and changing the resolution and it worked

Or there is the magical solution of re-installing toribash. Just saying.

in toribash folder there is file custom.cfg, when you open it with notepad it looks like that

ignore the first line, make sure that fullscreen is set to "0"
width and height are resolution, change it to the one you want, try something standard like 720X480 for start.
save it and launch tb.

This may sound crazy but I had the same problem and it was solved by me right clicking once while in game...

I always play with full screen ingame, but when I click a link ingame this glitch occurs.
for me it says fullscreen is turned off then and a border is added.
When I turn on fullscreen again it gets fixed.
you could try the above if you don't mind the real fullscreen
