I save a project in X3 then when I close it I'm asked if I want to save it again. This happens even if I make no changes. Only some projects do this. Corrupt file?

Some minor thing has changed since the last save. It should be utilized because something has actually changed. It wont hurt to say yes. 

No, but even if I open it and close it right away... without doing anything to it, I get the save window. I tested other projects and they aren't doing it so it must be a bug in that project.

it could be a plugin that uses randomisation, that would cause a changed notification

Obviously you will do what you want. I have had that pop up and if I think I should save that I know something has changed and I want to keep that change I say yes. If I don't want to save it I ignore it. Either way there is no harm in it as long as you know that you have saved what you want already.

This was my thought as well

It very likely is a plugin that is having a parameter changed due to automation when the project opens. Cakewalk has caught most of these, but there are still plugins out there that will trigger the dirty document flag.

^^^ This. It's not a bug in your project, but a bug, er, feature, of one of your plugins. If you really want to get to the bottom of it, copy the project and start deleting plugins (start with soft synths) until the problem goes away. File that information away for future reference, and whenever you use that plugin in the future you'll know to freeze that track to avoid this annoyance.

Thanks. Should have guessed it was a plugin as it's happened before.

Well, I could do what I don't want, I guess. But that wouldn't be as much fun.

I see this too, I open a project and it's immediately marked dirty. Do you use UAD plugins? Just looking for something in common.
