Default [Q] Helps

i need helps in opening Jblend apps~~
after installed the Java games, my htc touch 2 is able to open it. However, when it came to the gaming screen, my "Keyboard Icon" will pop up, and the icon bars block the selection keys.

Anyone can help me in this problem?

Furthermore, how can we differentiate what applications will cause the HTC touch 2 become disfunctional where only a hard reset is required.
