Hi,
As the title says I have this strange problem where none of the usual shortcuts work (Copy paste nodes with ctrl+c ctrl+v or even simply delete selected node with the “delete” key). Anything that add or removes nodes really. F6 and F7 still work and the keys are still recognize (I am able to copy paste in different fields within a node for instance, or delete characters I entered inside a node). Similarily I am unable to create meta nodes. I open the wizard, configure as wanted but when I click finish it does nothing (not even close the wizard).
Currently I have to right click copy right click paste and it is relatively painful 
Any help would be greatly appreciated!
Cheers and happy new year!
Alain
