Doesnt work for me no matter how i hit the button.

Have you tried punching?

Well thank you it didn't work and i got what you meant but i thought you might mean something else. And i did punch my computer at school and i got kicked out of the room. :'(
But now i cant climb the rope so its impossible for me. Ive tried to use the scroll bar but still no...Ive tried other hooks and they work somewhat but still cant beat it. Any way to fix the hook thing. Oh and if you need to know my controls are WASD,mouse,left click,right click. it says crouch and i cant just crouch so when i hold down it wont let me go up.

It's my attempt at humor.

Well, i lol'd, cause i thought it meant punching the mouse button.

That...was my reaction too.

I'm fairly sure that it was a pun on the usage of the word hitting.

DO A BARREL ROLL!

Random as...Well a big black guy walking out of an alley wearing all pink tight clothes covered in blood and holding and ice cream cone...or just my huge post that was useless which i got a warning for.

Git back on topic or ferocious cat will eat you.

@panda - Are you holding crouch and scrolling at the same time?

nope...Got it to work for me in my own special way not necessary to talk about.
