You simply can't admit that quite a few people experience problems with OS9 running under OS X, can you? Not even when the evidence is shoved in your face... Sheez ... what a waste of time it is conversing with a blind zealot...
It is simply not my experience. And, Bush, I am far more experienced at this than are you. I have quite a few clients running OSX and still running classic apps... they have no problems.
Even that website with the "problems" (90% of which were questions of "how do I do...") contains a grand total of 537 questions... dated from January 20, 2002 to March 14, 2005... and there are over 14,000,000 Mac OSX users. That does not make for a major problem.
As we have stated, Classic mode in OSX actually runs classic apps faster and better than a native OS9 environment. Does it have problems? Yes... many of the same problems that caused Apple to move to the UNIX based OSX in the first place. That is the experience of 99% of OSX users... not the 1% who may have a problem.
