FB II runs fine under 10.3.3 on my iMac, so a G4 Powerbook should work.

So, if I understand, you have a Classic app created with FB II that you 
want to run under Classic in 10.3. This is likely to give you a lot of 
grief because FBII allowed (and even encouraged) non-standard 
techniques that cause apps to crash in X. Accessing low-memory globals 
and others are a big no-no in X (see the FBII to FB^3 conversion doc). 
Most likely the app is trying to touch/alter memory it shouldn't and X 
is swatting it down. You can verify this by looking at the 
crashreporter logs for a start. You will probably need to convert your 
app to FB^3 (and even if you don't it makes good sense longer term) and 
remove/convert all the bad things FBII allows to methods that are 
officially blessed. What I don't understand based on the information is 
why it didn't fail in 10.2.8. Again, I'd check the logs first. Also, if 
the app is converted to be built with FB^3, you can run the debugger 
and find out where you crash very quickly.

Hope some of this helps. Basically, we need more information.

Start at the beginning. Look in the crashreporter logs.
