Dear all,

we have updated our Quintiq version to the DELMIA Quintiq Release 6.4
On our old version, to synchronize the graphics, we had a window where we selected the things to synchronize together:

but on new version, this windows is not available. 

I got it the first time i've synchronized graphs but since i've done it, nothing happened when i clic on the option on the graph and i can't acces again to this window.

Can you help me? 
Is this synchronized window accessible somewhere else?

Many thanks
