I do not experience that problem on my A4000T with 060/50 and the YAM program. Are your 680x0.library files up to date? Curious, why are you running OS 3.9 with BB1? Why not BB2??
Don't get me started on Outlook Express. That software is such a big pile of poo! I have multiple identities configured in it (myself, girlfriend, her mom). Sometimes when I pick any of the three, it only opens up one of the accounts regardless of which identity I picked from the startup list. Have to reboot (go figure) to get it to cooperate. BTW, this is IE 6 with OE 6 running on Windows e(X)tra (P)oop with service pack (read: huge pile of bug fixes, with lots more new bugs, too) 1 installed.
