NXi G1000 Cursor issue

I’m trying to build/edit a FP in the MFD. From watching training I’m of the understanding I should push click the FMS center knob with left mouse while simultaneously right clicking to get the cursor to drop down into the plan. Does’t, On the PFD it works find, I get the cursor to drop into the plan by rotating knob which has always seemed the way to get the cursor live. When I rotate the outer FMS knob the MFD scrolls through MAP WPT FPL pages, all good. Inner knob does nothing. Clicking center of button turns knob yellow ( using lock on acessability setting). Pray tell, what might I be doing wrong here. Thanks for any help getting this old dinosour pilot into the “modern era”. Cheers!
