Virtual Keyboard only shows after two taps

I have an app that has only one Webview and some buttons. On the webview I show a website that contains one textbox.

Sometimes, when I tap the textbox the virtual keyboard does not show, and I have to tap again. This only happens on OS 2.1

Has anyone else faced this? Anyone have any idea of what may be causing it?

I tryied removing focus, requesting focus, invalidating the screen, etc...

Please, any sugest开发者_开发知识库ions, or battle plans on how to defeat this bug would be greatly appreciated (Really, this bug is very annoying)

Thanks a lot!

It might be that the area your text box is in has a onMouseOver event. This would cause the first touch to activate that event and the second touch to activate the keyboard.

I see this all the time on my iPhone browser.
