keyboard input problem

[AlfaM03]

hi guys! i reeeeally need your help on this. i usually play my ppsspp on my eeepad transformer tf101. and i use my keyboard dock to input controls on my game. i then downloaded a fairly new build. 0.9.6.778 i think it was. that was last week and ever since i installed and updated to the new build my ppsspp can't register inputs from my keyboard's alphanumeric keys(esp the LETTER KEYS) but can still register inputs from my arrow keys, spacebar, enter, shift, etc. it detects the inputs from my alphanumeric keys when i change the control mapping but when i start a game, they dont work. :/ anybody experiencing this issue as well? HELP!
