Thanx stavs82

i did wat you said, but im not seeing any white arrow. I'm working with V5.0 and i know for sure that i just that white arrow before with V4.0. But when i pres the T Key nothings happens.
The T key is a shortcut to the show manipulator button. if i press this button it says there are no settings defined for this tool

Can someone help me with this?

Thanx.

Edit: something else wat i dont understand, mij joints are way to big for mij model. i did check the option scale compensate in the Joint settings, but this didn't help.

these little problems are starting to get to me
