Hi Ben.
Mine was a very simple fix as I had plugged one monitor into the graphics card and the other into the motherboard, and it was the mother board one that was causing this issue. Plugged both into the graphics card and it fixed it.
However, I have since been contacted by the local distributor tech office, saying that since a Jan / Feb windows update other users had been experiencing the same issue, which wasn't caused by where the the monitors are plugged in.
Unfortunately, if both your monitors are plugged into the graphics card, I dont have an answer for you. All I can say is that the powers that be are aware of the issue and are hopefully trying to sort it out as it is a bit of a game breaking bug.
As a side note I think I have had more issues with VW19 than any other version of VW which is saying something. Im still using VW18 for some projects as Im reluctant to advance any on VW19 for fear of finding something else.
If Im contacted again I'll add to this post, with any news.
I hope you get it sorted.
Cheers
