Comment 10 for bug 1108989

>>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?

Yes.

>>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.

On Unity, you have a nasty bug. i.e. If you have created several projects, When you select one (not the last), it will be always the last which will be opened. This issue touches not only Openshot but Inkscape, Dia,......

But in practical experience, the new/open project replace the previous in the same windows.
You should have a Advertising box for save the project, always this one.
