Well the newer mice are smooth but have 2 buttons so depending on how new your mouse is will determine the buttons. Open up minecraft and go to the controls menu and click on "Use Item" and then right click if "Button 1" appears then you have a 1 button mouse and you will need to set that to a different key. Or just buy a new mouse.

Is it a 1 or 2 button mouse?

Well I just signed up today and I didn't realize that there was a modify button, derp. If there was a download for the source code I could do it myself, but do you know what I'm saying about the redundancy in files.

Make sure you can right click and if you can the check the game controls and make sure you have Use Item set to Button 2[i/] on your mouse, or just set it to another button that does work.

Also when is Tekkit 2 coming out? MOD EDIT: USER WAS PUT ON PROBATION FOR THIS POST

For the Vanilla, Technic, and Tekkit modpacks you should make a global texture packs folder that is shared between them, because I want to use the same texture pack, which is like 70MB and 70*3=210MB. That's a waste of space if you ask me. You should do the same for the binaries and libraries since they are unmodified and required for all mod packs.
