I shut down all virtual machines before upgrading to Fusion 3. On boot-up, the new vmware 3.0 tools were installed. Is there some reason that the vmware tools 2.0 need to be uninstalled first? Perhaps you can make the tools installer take care of that issue.
The tools installer normally takes care of this issue, but we had a bug in the tools installer of the tools that shipped with Fusion 2.0.5.
The VMs are slower to load.
What do you mean by "lo load"? When you start the UI?
Once the progress bar runs its course, the Macintosh "spinning pizza" takes over. Fusion 2.0 did not cause the pizza to appear, and the pizza seems to prevent the user from doing anything else (outside of Fusion 3).
How long does that last?
The Fusion 3 application is more sluggish to quit (File -> Quit).
Yes, we are working on that.
Regarding the reappearance of the window for the last VM used, this behavior appears to be new. Preventing it is not an option in the preferences or the Window menu. It's confusing. Why did you need to make this change?
We made this change because it follows the toaster principle: you set the time, and it does not change when you load bread into the toaster, days and days after. And anybody can check the time, ad change it if they don't like it. The Fusion 3 UI behaves that way, because it is the principle of least surprise: whatever was opened when you quit the UI is re-opened when you start the UI.
We didn't introduce a preference for that behavior because we don't want to create an explosion of preferences (i.e. create a new preference every time we change the slightest thing). Our role as UI deveopers is to decide what makes sense for the majority of the users, the Apple way. Yes, it behaves differently than Fusion 2, but it behaves in a better way. Right now it is not the new behavior that annoys you, it is the change. The fear of change will wear off after a while, and you will learn to appreciate the new behavior. Trust me. People reacted the same when we changed the snapshot paradigm in Workstation 3.0 (i.e. they complained), but now they would not want to go back to the old way for anything in the world.
