I have the following rig -

Home built system:

AsRock MB
I5-4670K CPU
24 GB Ram
GTX 1060 6GB KB
Logitech G700s Mouse
Corsair K95 KB (Not RGB)

When I launch Pinball FX sometimes it recognizes the KB sometimes not. Rebooting the machine usually fixes the issue. I do not have issues with any other game or app. I have tried with and without the Corsair KB utilities installed. This issue existed prior to the Win 10 creators update and still exists after the update. Tried resetting win 10 to default state did not help. Any suggestions?
