I found a pattern to that weird site thing ya mentioned. It seems to be a side effect of the auto save feature, where the text box seems to kinda "lock up" for a second. It's right before it does its auto save. If ya don't touch anything for a sec, then when the auto save text starts to fade out, the keyboard is freed up again normal. On my tablet it sometimes even moves the cursor back a couple spots haha! It doesn't seem to always do it, weird. But it's always right then. So far I haven't double posted, but I could see where it might do that too maybe if ya hit "post" right when it's in the auto save lockup.... Maybe idk lol. Doesn't bother me any really.
