BI4.1 Formula : Edit + Drag & drop

1. On BOXIR3 we could type the beginning of the formula and a list of dimensions was suggested, but not anymore on BI4.1 ? 
2. And we can't use the "drag & drop" to insert "Available objects" in a formula ?
   it doesn't work anymore ...
3. And one more : to edit the formula normally we can use "Ctrl+Enter", but when we do it, nothing happens ... ?

Maybe did we miss some parameters in the CMC ?

Thank you already for the answer
