I have got a little problem with my joints, when i put the mouse on the shoulder for example, it doesn't directly select it so i can start contracting/extending etc... i have to click it once and wait like 1 sec so it selects then i can start moving it. can someone please tell me what to do?

hey, you can try disabling background click and changing your mouse buttons under options.

I tried, it didnt work, i ended up restarting the pc and it worked so yea, dumbest solutions are always the best xD thanks anyways!
