BMS 4.3.3 and win 10 issue

Hi guys,
I update my computer to win 10 and install BMS 4.3.3.
The installation goes well and I can start instant action without trouble

After I press ESC and e to quit instant action, it went back to the instant action page but the keyboard are not responding.

The mouse is moving but nothing happens when I lest click the mouse.
The keyboard is not responding at all.

The background music is still on and runs smoothly.

Can anyone tell me what is going wrong?

I have read something about resolution conflict between the game and win 10, but I am not sure if this is the reason.

Does it behave differently in TE or Campaign modes? Or do you only fly instant action. I assume it wasn't behaving like this with your previous version of Windows.

Would be worth your time to have a look just to see if all modes are effected or not. Instant Action has been in a sort of broken state for a long time,
and BMS team makes no efforts for improvements here. You could try installing in Win7 compatibility mode. Run as Admin.

4.33 is no longer supported since the release of 4.34 so you probably won't get much help over at the BMS forums, but nothing ventured...nothing gained.

Hope you get it sorted!

Thank you for the reply Schnidrman.

I have find out the answer.

I installed a Chinese WIN 10 and the default input is Chinese keyboard.

Everything goes fine once I add a US keyboard as another input method.

Hope this will help others with similar problem.
