I'm under a bit of a time crunch. The sooner I can find an answer the better.

I'm using DP Pro X9, and quite suddenly, I no longer can turn visibility of layers on and off. This actually represents a bit of a disaster for me at the moment. Probably something quite simple. I can lock or unlock layers individually but the little eyeball seems to be grayed out and inactive.

Please help me out of this jam.

Regards,
Alan
