You don't need a special program, but I suggest Firefox. What you do is 1)Open up two windows, go to runescape on both and go to same world 2)Minimize both so you can see one at the top half, the other the bottom half of screen 3)Type in the login information, but DON'T click login yet. 4)Make sure you can see the login button on both screens. 5)If you have a fast mouse, it shouldn't be hard, but you have to click both really fast, or else it's very hard, as you might have to reenter login information again if it messes. up 6)This works for me 99.9% of the time, and I've done it for over a year, and never been caught ;D
Well. What i did (havent done it since trade limit) was to open up two RS windows, one in normal Java, and one with an Unsigned applet on the same world. Then i just logged in from there and it worked.
EVERYONE HERE FAILS LOL!!!!!!!!!!!!!!!!!! some sad crap right there. STEP 1! GO TO Www.runescape.com STEP 2!! click play runescape!!!! STEP 4!! scroll to the bottom of the page on detail select menu until you see "Select Java Version - only change this if the default doesn't work" click it and select unsigned applet using default java STEP 4!! open runescape. This way, you can multi log on the same world to, ORRR get eliteswitch which had a multi log feature (last i knew)
