Ps/2 to usb and simultaneous keystrokes

[pj_martins]

Hi all, I have my keyboard and mouse connected to one of those ps/2 to usb adapters (2 ps/2s to one usb) using windows 7, but now I'm having the following issue, when I hit two simultaneous keystrokes, it works fine but as soon as one of those keys are released, it loses both of them, eg. When playing a shooting game I can run fine using w and shift simultaneously, but as soon as I release shift, my character stops. Is there a setting in windows 7 that could be causing this, or a driver that could solve the issue?

Any help will be appreciated.

I had a problem using those PS2 to USB adapters with an IOGear USB KVM switch and decided that it was finally time to go out and buy a USB keyboard...

Eureka! this adapter is working with games and have memory for arrows keystroke:

I tried other 2 adapters (with cable) but they didn't work, when you pressed 2 arrow keys and leave one the movement in first shot games stopped.
