We (at work) have just upgraded to InDesign CC 2017. Our setup is like this: couple of Mac's (creative) and a couple of PC's (copywriter).
Until CC 2015 the IDLK (InDesign Lock File) prevented "the opponent" to enter the InDesign doc. while is was open by anyone in the Mac/PC combined workspace.
In CC2017 my Mac can't see PC generated IDLK file and PC can't see Mac generated IDLK.
It means that, while I working in a InDesign doc., my colleague can open the same doc at the same time... it courses at lost of trouble!!!
Now what??? any ideas?
By the way. We are all working on a server
