I have checked with Precise on a different PC (but 32 bit, yours is 64 bit I see) and I still see the problem, which I find surprising. I have not got a 64 bit installation to try it on. Are you running Unity?
When I say File > New Project it replaces the current project with the new one. Is that correct or should I then have two project windows? I particularly notice that if I open an existing project, make a change but do not save it, and then open a new project, save and quit, that I do not get warned about closing the first project without saving it, which makes me wonder whether it is the first projects threads that are getting left running.
