I will also take some time to simplify the problem. The crash occures during copy/paste. it does not matter if you use the menu command or keyboard shortcut. The problem is completely random. You can copy and paste for an hour and then without doing anything different, it crashes. Once you go back and copy/paste the same item that crashed it, it then works. I have worked on about 6 different files with some starting from scratch and it happens on each file. I do not believe at all that this is file specific.
There is nothing I can do to make steps that will crash it on demand. it is a completely spontaneous event.
Further to this I am getting quite tired of the blaming and attitude talk. Comments such as "that is the price you must pay for working with the newest version of Apple's operating system" serves no purpose except to further infuriate users that are already ticked off. As stated, this is not an option for people that just bought new hardware. BTW. I have no problems with 10.2 or any other piece of software running on it. My problem is solely with Vectorworks. So before making snoody comments about other companies, I would take a look in the mirror first.
