Ok, working in MX 2004 ( but I think that it was this way in MX ) trying to edit the gradient of a rectangle, but every time I click on it and go to the "Color Mixer" it changes my gradient. Basically my question/ problem is how do I edit an existing gradient without starting at scratch every time?

Either this is one of those things that I forget and have to look up everytime or it can't be done! Please tell me I'm an idiot and show the way!
