Done it, it's buggy gets corrupted, don't recommend using it.
You can command + tab or command + shift + tab to cycle through, and Command + H will hide Carbon apps (incl. AppleWorks 6).
The more of Classic's "neat" features - most of them were the causes of fragmented memory and instability. Turn off any background processes and you'll lfind that Classic runs better and even not under X 9.0.x is more stable and doesn't "lose" or suffer from memory becoming fragmented - a very very small amount is lost over time, but turn on conrol strip, folder actions, time synch, indexing, etc and you'll find those memory "problems" and "leaks" and fragmented.
Classic needs very few extensions to work properly. Fewer the better. Tear-off application menu isn't one of them.
