i have, since i found what i thought was a bug in the way it used the mysql interface..
when i made the change, the problem no longer happened.. and it wasn't a hard/fast bug.. ie: reproducible 100%.. it was elusive and left to chance kinda dealio..
i assume that change (or something similar) is what is in 7.5.5
Linky Poo to what i ran across.. in reality, it all started with birthday emails (for me, at least
)
