big problem to use event "touchstart"

hi !

i try to make a website by using openlayers for a map on my HTC-Desire.

My source you can find in my develop-example.

there i inser following source

  1.  map.events.register("touchstart", this, function(e) 
  2. { alert("touch start"); });

but if i touch simylar on the screen (map) the message will not show.

may the wrong event i want to call ? did i use "tab" ???

could you help me?

regards Jan :-)
