[Move and resize impossible]

Hi !

So i'm start using Affinity in free version to test it before bying (on PC Windows 10) it and i have a basic problem, it's totally weird : i can't move or resize any text or object ! Despite i select it , keep it and try to slide , nothing happens! Neither for move or resize. ( its not locked in the layers list or anything like)
I searched everywhere in options and help guide , and i can't find what is the problem for this really basic function! I despair! 

Hope someone can help me. Sorry for basic english i'm french.

Thank you !
