I just upgrade from 0.4.22 to 0.4.24.
For fun I tried to sell 1 bitUSD and saw an error "insufficient relay fee".. which looks the same as others had a while back, described in another thread:
Help: insufficient relay fee. On restarting BitShares that disappeared and it appears to have gone through.
Then there was an alert suggesting some form of stacktrace error.
I wonder that alert could speak plain English, if it is going to alert the user.
