i can't hold or relax muscles individually i can still use c to hold all muscles but thats all otherwise its contraction and extension only i have tried reinstalling but it did not help all my friends aren't having this problem.

Have you tried hitting X while mousing over a joint?

get toribash 3.88 or 3.86

ur mouse bottuns must be on the wrong number option man go to options then in the mouse bottun option type 1 hope i helped

Ok

If You click and it only extends and contract, you can use the "c" to hold or relax all.
"x" Move ur mouse over a joint and click the button x. It will relax or hold it.
And with the button "z" is extend and contract.
"L" Move over the wrist ur mouse and click the button L ( This is usefull when u have ur 2 hands gripped together or when u cant see ur hand and u see ur wrist ).

Press "E" in a replay to edit a part of it.
Press "P" to pause or play ( P + Shift it passes one per one frame with a space click )
Press "f" to save replay.

etc.

Thank you~
