As much as I would like to expand on the details here, I am not able to find relevant information about the root cause of this problem.

I am having this issue with my blackberry Webapp which I built using JQM. After few times of navigation from page to page, the application becomes unresponsive on the destination page and I am not able to scroll up/down using the touchpad.

If someone had this problem or some clue to the resolution, then that would be helpful.

Edit: after doing some research I was able to narrow down the cause of the issue. I am having an issue with focus-based navigation. As I lose focus on the page elements (buttons, input fields, etc) after few transitions among the pages.

Edit I had to switch back to the cursor based navigation as it is much faster and do not have the issue faced by focus-based navigation. I removed the entry:

<rim:navigation mode=”focus”/>

from the config.xml file

I found this entry on the blackberry fourms but it haven't solved my problem despite the fact I upgraded my WebWorks SDK to 2.0 from 1.5
