Slow/jumpy cursor in main menu (Windows 7)

[CitizenKane]

Hi

I'm trying to play the latest version of AlephOne in Windows 7 (I've generally played it on Macs in the past).

I have found that the cursor is very slow and jumpy while in the main menu (regardless of the scenario loaded), to the point that it is difficult to navigate the menu and click any options. However the game itself runs fine during play. The issue only arises in the main menu.

Anyone experienced this before or know what it might be?

Full specs:

Motherboard: Asus ROG Maximus IX Hero
CPU: Intel i7 7700k
GPU: Nvidia GTX 980 Ti Hybrid
SSD: Samsung Evo 960 1TB
RAM: Corsair Vengeance LPX DDR4 3000 C15 (2x8GB)
Cooler: Noctua NH-D15
PSU: 850w
Monitor: Asus ROG Swift PG279Q 165Hz IPS
Keyboard: Razer Blackwidow Elite
Mouse: Razer Viper

Thanks

I got an outta the box Windows 10 laptop and using 20100408 version has no problems on this computer.
I tried Eternal 12 and B of BL and both worked.
One thing this computer does do - and I know it's the computer cause neither o my others do it -
is that at random moments whatever key I'm pushing "sticks" as in sticky key but I have sticky keys off
and the only way to regain control o the keyboard is push that very same key again.
Sic fit.

Well, hold on, I just noticed W7. Lemme go find a W7 and try it there.
