Input locked after some playtime

What steps will reproduce the problem?
Play Oniken with hourglass. After 2~3 minutes the game controls stop responding 
and lock in the last input you pressed before the issue.

What is the expected output? What do you see instead?
The input should work fine during all the gameplay.

What version of Hourglass are you using? Did the problem happen in older
versions too?
Using r81. Same issue on r78.

Which game are you running and which version is it?
Oniken v2.0

Which version of Windows are you running?
Windows 8.1

Please provide any additional information below.
There is a demo version of the game on Steam and in 
http://keyo.me/oniken/Oniken_Demo.zip

1) Open the game launcher without hourglass and enable software rendering. 
Close the launcher.
2) Don't run the game launcher with hourglass. Run Oniken.exe instead inside 
the DATA folder.
