Two button configuration does not allow for simultaneous button press

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set Num button configuration to "2 buttons"
2. Load game in landscape mode.
3. Tap in between the two buttons "x" and "b"

What is the expected output? What do you see instead?

The game loads with the two buttons, but tapping between results in no input. 
But some games hide an additional "two button" press to produce an additional 
action (e.g. Final Fight characters produce a "special move.")

What version of the product are you using? On what operating system?

imame4all v1.0.9 on iOS v4.3.3

Please provide any additional information below.

The two buttons should allow for a simultaneous press by tapping between them. 
A workaround is to use the 3 button configuration but this adds an additional 
button on screen that only takes up screen real estate when playing in full 
screen.
