Well I recently downloaded toribash and when I try to change
options it doesnt change when I clic ok, and when I mark
fullscreen the cursor gets crazy, I installed it 2 times already.
help me please

well, game rules dont work when a replay is on.but the full screen cursor thingie, i can't help you with

what version are you using
3.83 or 3.84 betas?

if betas the resolution have problems

just re download and re install again

remove the program first before re installing though

I have 3.82 it said it was the newer one

well you can change the resolution to a good one to fix the cursor like i did
but tooked shitty time though

now the problem is that I can't save the things I change on options

That's a known bug in 3.84 beta 5 if you check out this thread.

I'd advise getting a different beta client or waiting for a fix.

Thank you.
And one off topic question,
what is the shader mode?

With activated shader mode you will have better graphics in tb.
everything is shaded...
