Today I've had three confirmed double posts occurring in AF. They are all within AS group forums (different groups), from two different users (one double posted twice and the other once) and both are reliable/experienced users.
In all three cases...the date stamp on the doubles is milliseconds apart. I'm asking all the usual questions (browser, OS, double click?, etc).
Other people are posting just fine even in the same forums. Not sure what I'm looking for so any suggestions would be appreciated.
