If I want to post on here using Chrome on my Android tablet I have to click the HTML button and type in that window, click update, then add in the carriage returns. Unless at least one character has been added this way, the normal edit field won't accept
any key presses.
If I use Firefox on Android, the normal field works sort of, then it starts duplicating key presses and you can't paste. The cursor jumps around as well and you're suddenly typing in the middle of another sentence.
I've resorted to typing in a text editor then pasting into Chrome.
All really painful.
