This is a hardware issue, see MC-54194

Comment by Kumasasa [ 01/May/13 ]

What happens if you open an editor and press and hold W & A and press Space ?
I get

awwwwwwwwwwwwwwwwwww_

(Replace _ with blank)

If you don't see the blank when pressing space, your keyboard cannot handle that combination of keystrokes.

Comment by Ultimate Omicron [ 01/May/13 ]

Again, depends on the keyboard. Many nonstandard keyboards like laptop or wireless devices have a lower simultaneous key limit, and the spacebar is a key that usually demands more. So you can't usually combine more than 3 keys if one is the spacebar.

If the mouse button is participating in the problem, then you might have either a laptop setup where the keyboard and mouse participate in the same ps2 connection or a wireless relay with the keyboard as middleman.

Just throwing ideas.

Comment by David Buddy [ 29/Apr/13 ]

How is this closed because it can't be re produced. To reproduce this bug hold down W & A and than left click, or push space bar!

Jon Trollsten: Don´t see a reason to upgrade, my fps is high, not sure exact, and I never experience lagg or else, but keyboard is probably the solution... even though I love the one I have and won´t get a new one...

Comment by Jon Trollsten [ 22/Jan/13 ]

Maybe a better keyboard with better ghosting

Comment by Jon Trollsten [ 22/Jan/13 ]

WOW. Geforce 7900 GTX? You really need an upgrade and more RAM. I know that is off topic but what is the ~FPS that you get?

Comment by Ultimate Omicron [ 08/Jan/13 ]

Many wireless keyboards have trouble combining multiple keys. Try remapping the jump action and see if it still happens.

Comment by Rockyfelle [ 06/Jan/13 ]

Its does NOT work with left, but works with anyhting else, like right

Comment by Nicholas George [ 06/Jan/13 ]

right+forward and jump? you said left

Comment by Anon Ymus [ 06/Jan/13 ]

Try getting LWJGL 2.8.4.

Comment by Rockyfelle [ 06/Jan/13 ]

No mods, they keyboard is wireless but as said works with right+forward and jump

Could also be your keyboard. Is it wireless? Some wireless keyboards can only handle very few keys at the same time.

Comment by Kumasasa [ 06/Jan/13 ]

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

Comment by Anon Ymus [ 06/Jan/13 ]

Cannot reproduce. Perhaps it is an issue with your LWJGL or your controls. Please attach your options.txt.

Comment by Nicholas George [ 06/Jan/13 ]

Not true, I tried and it works I can jump, you must have mods affecting that ability!
