On a touchscreen, tapping on an icon in the dock launches two instances of the application. Only one instance should be launched. Tested with multiple applications including gedit, gtkhash, nautilis.

In order to test my touch screen to see if it is some-how registering two clicks instead of one, I used xev. I tapped on the xev window, and as sown below, only one tap (press and release) was recorded.
$ xev -event button
Outer window is 0x2e00001, inner window is 0x2e00002
ButtonPress event, serial 25, synthetic NO, window 0x2e00001,
root 0x211, subw 0x0, time 7842931, (130,118), root:(327,304),
state 0x100, button 1, same_screen YES
ButtonRelease event, serial 25, synthetic NO, window 0x2e00001,
root 0x211, subw 0x0, time 7843049, (130,118), root:(327,304),
state 0x100, button 1, same_screen YES
I could not test taps on the Ubuntu Dock in using xev.
If someone could suggest how I can monitor events generated by the dock, I will run the test and post the output?
