A real Handy use-case for TW on a Kindle is to run TW in a browser (to a remote node.js TW) to take notes while reading an e-book. But if the editor won't allow editing existing text, one had best not save any typos!
The issue appears to be in a core Kindle component, because the behavior is the same with Silk, Chrome, and Firefox.
Any ideas for a work-around?
It isn't an Android issue. Editing works fine on my Android Cell phone
