why waiting seven seconds after button touch for touch detection in phonegap

[headkit]

hi there!

why do I have to wait seven seconds after I touched a button inside my sencha-touch/phonegap app on iOS for the touch detection to trigger my panel-slide or even make the button change to .x-button-pressed?

thnx!

I found out that the problem was a simple CSS entry:

.x-button.x-button-pressed, 
.x-button.x-button-active, 
.x-toolbar .x-button.x-button-pressed,
 .x-toolbar .x-button.x-button-active {
    -webkit-box-shadow: inset #AAA1A1 0 0 39em, rgba(255, 255, 255, 0.1) 0 0.1em 0;
} 

but how could INSET (or the 39em?) kill the performance like that?
