The Classic environment is a feat of software engineering. It allows legacy software to run unchanged within Mac OS X. Unfortunately, it is impossible to completely integrate two completely dissimilar operating systems, so users are likely to notice both visual and operational oddities. Some of the more annoying problems can be easily worked around, but a hybrid OS X/OS 9.x system is not likely to appeal to first-time or casual users. Try to adapt to working completely within the OS X environment with native software. If that isn't yet possible, remember that you can always boot directly into Mac OS 9.x or OS X.
