I can't really say.
I can say that I run several triple monitor systems running the current Windows 10 full release (not fast track or any of that crap). I run Fences on all of them and I have none of the reported problems. This thread, or others.
I find it odd that I read all of these threads of problems that I don't have. I assume it is connected to some software that I do not have that others do have.
I know that this doesn't help much. But I run almost every software that Stardock offers, and have for years and years, with no major problems. Spanning XP, Vista, 7, 8.1, and 10.
Odd, I know.
For what it's worth.
