Creo elements/direct modeling express 6.0: selecting surfaces

Hi,

I am using creo elements direct modeling 18.1 for  my proffesion but at home I use Creo elements modeling express 6.0 for hobby projects for several years now.

Since a few weeks now it is not possible anymore to select surfaces by clicking on it. To move, drag, change properties etc... this is very inconvenient.

I tried to change the select settings but without succes.

Does someone did have the same experience or better have a solution for this ?
