...also sometimes it won't let me "modify" posts. It tells me that I've already posted my message. But I haven't!
Frustrating!
Same here. I can usually come back later in the day to correct it, but I don't always remember.
And I also get that problem with getting "bounced-out". On one page, I'll be logged in & on the next page, I'll be logged out, logged in, logged out, & so forth ad nauseum.
I can't see where there's any connection between the two, though.
