First, the general question: From a programming point of view, what does a `VM aware' application do that a `normal' (at least, a pre-7.0 normal) application doesn't do? Now, some specific questions: In particular, I'm interested in what happens with some specific apps: MacDraw and Think C. The 7.0 compatibility checker says that MacDraw and Think C won't work with VM, and recommends that VM be turned off when using those applications. But a call to Claris produces the following statement from a tech support person: MacDraw will work fine with VM, but use at your own risk, since the SQA group ran into a (possibly obscure) problem with it. That's why it is flagged "don't use with VM." Now, what about Think C? Does it really run with VM, but might cause problems? Or does it die horribly and with certainty? I haven't been able to try it yet, since I still have 4.0.1 and need to get 4.0.5 before I can run it at all. I did briefly bring up MacDraw with VM on, and saw no overt problems. But I didn't stress test it by bringing up all the rest of my applications at the same time :-). _____________________________________________________________________________ Disclaimer: Last time I posted a question, our newsreader posted multiple copies of my post. I've been assured that there is no current problem with the newsreader or with posting. But, in case the same thing happens again, I apologize in advance for wasting bandwidth. I would like to know if it happens, however, so I can provide evidence to our sysadmin that there IS in fact a problem. _____________________________________________________________________________ "Never let work interfere with your reasons for working."

That's why it is flagged "don't use with VM." According to an expert (my wife the SQA person who tested MacDraw II under System 7.0) MacDraw II 1.1v2 should work fine with System 7.0. Testing was limited to checks for functionality of the product under that system. She says that she found no problems with VM, she hedges a bit on 32-bit addressing (it seems to work fine but it hasn't been tested to the limits).She didn't have a chance to *thoroughly* test it (they're busy testing the new MacDraw Pro), but never found any serious problems with it. Claris Tech Support may have given you the advisory based on the fact that a really thorough test wasn't performed. It's probably good advice. -- michael -- Michael Peirce -- outpost!peirce@claris.com -- Peirce Software -- Suite 301, 719 Hibiscus Place -- Macintosh Programming -- San Jose, California 95117 -- & Consulting -- (408) 244-6554, AppleLink: PEIRCE
