You are correct, Toaster no worky with WB3.9. That's why I got the TruIDE as it can dual boot and I'll be running WB2.1 on the second CF card. I'm still working things out with the 2GB CF test card at the moment. Still wondering what to do about the 2 dead 4GB CF cards I got from... cough... cough... you know who that were supplied with the TruIDE. Anyways getting off topic... (I should start a new A2000 thread - so many Q's) hope we can continue bridgeboard alternatives here. 
Why? I don't know... it's fun.
I don't know where this story comes from that the Toaster does not work with OS 3.9. I have an A2000 and an A4000 with Toasters that work with OS3.9. That is until the A4000 Toaster went poof one day but it ran for a couple years with OS3.9 just fine. There is an issue with the newest Toaster installer that it overwrites some libs with older ones but restoring them after the install completes puts everything back where it should.
