We've been pondering a bit on that vague slowness in the posting window on some android units...  What features are unique to that, which do not exist on the edit post window? 

The slowness is visible in both post window and PM window, but never in the edit post/PM functions. Thus logic should indicate the culprit being a feature that is in the former but not the latter.

We vaguely recall you mentioning an autosave feature. could that be related?
