C&C: Tiberian Sun menu overflows screen, and submenu windows won't display (W10)

There are no official patches for the win 8/10 problems, I made a patcher that solves the problem though. You can get it here: http://cnc-comm.com/community/index.php?topic=3438.0

If you don't trust me (my patcher) then I could also explain you how to solve it using the Microsoft Application Compatibility Toolkit.

I don't know where you have the 75% from though, I haven't heard of many people who couldn't solve the problem using my patch 🙂
